How to copy, select and search text in ePub books using SumatraPDF

SumatraPDF has been our go-to PDF and ePub reader for quite a few years, and I’m sure that some of you may be using it too.

I’ll admit to using Microsoft Edge (Chakracore) occasionally to quickly view a document or two, but the solution is not as fast and usually not my top choice when it comes to that.

Tip: check out our EPUB reader overview here.

How to copy, select and search text in ePub books using SumatraPDF - issue

But with the new Edge-Chromium browser dropping support for ePubs and the fact that it will replace the other Edge, I stopped using it as a document viewer and rely solely on the light-weight reader.

Recently, a friend of mine asked me to help with an ePub. This was a textbook which he was trying to take notes from. But the problem was that the ePub’s text could not be selected, hence there was no way to copy content from it.

Now, if you find yourself with an ePub and want to search for text,  you may notice that the toolbar at the top  (which has the find tool) won’t be visible, so you can’t do that.

There is a very simple way to fix this, and it only takes a few seconds.

How to copy, select and search text in ePub books using SumatraPDF

1. Click on the menu button (in the top left corner) of SumatraPDF’s interface

2. Navigate to the Settings menu and click on Advanced Options.

3. A text document named “SumatraPDF-settings.txt” should open in Notepad (or your default editor).

4. Look for the line which says UseFixedPageUI = false. It’s under the EbookUI settings.

5. Change the value from false to true, so it should read UseFixedPageUI = true.

6. Save the document, close SumatraPDF and re-open it.

Load the ePub document again in the program, and it should now have text that is selectable and searchable. That was easy, wasn’t it?

How to copy, select and search text in ePub books using SumatraPDF

There is a caveat to this. It breaks the document’s formatting, but the extent of it depends on the ePub.

That’s because the program doesn’t support XHTML completely (ePub is based on HTML). So, when you force the change, it renders it in HTML and the CSS style elements which aren’t supported are broken. If your ebook does not contain a lot of CSS formatting, it should work perfectly fine. I tested this with some free eBooks from Gutenberg and some textbooks, and the latter had some issues. But, there’s an easy solution for this as well.

Even if the document does not display perfectly, you may still use the feature to copy the text that you are interested in before you restore the preference to its default value.

SumatraPDF breaks eBook formatting

SumatraPDF’s stable version was updated sometime in 2016. But the program is still actively being updated frequently on the pre-release and daily builds. Download the latest one, and try the same fix which we mentioned above for enabling search, selection, etc. And you’ll find that the new builds may preserve the eBook formatting.

An alternative would be to use the Calibre program for reading ePubs. It does offer selecting text and the other options natively. But it has always been considerably slower to load, at least for me.

How to install VMWare tools if the option is grayed out

I use VMWare Workstation Player primary to run Linux but a few days ago I wanted to install a virtual copy of Windows 10 to test some upcoming features. Virtual machines are great for testing operating systems or programs as they can be set up relatively quickly, don’t alter existing installations and don’t interfere with the underlying operating system.

How to install VMWare tools if the option is grayed out

I got the ISO using Martin’s guide and the installation went fine. But then, I noticed that it didn’t install the VMWare tools like it would normally do.

One of the important features that these tools add is the ability to copy data from the virtual machine to the host operating system or vice-versa. That’s how I actually came to know that the tools weren’t installed, it didn’t let me move some folders from my main Windows 10 to the VM version.

I knew that I had chosen the option to download VMWare tools when creating the virtual machine. I even remember the message log displaying the notification that the tools had been downloaded. Oddly, when I clicked the Manage option the install VMWare tools option was grayed out.

Hoping to find a fix, I began to look around and came across official documentation on VMWare’s support portal. According to the page, the virtual CD/DVD drive should be set to “Auto Detect” so that VMWare would let the user install VMWare Tools. The option which I wanted to change in the virtual machine’s CD/DVD drive was set to use my Windows 10 ISO and I couldn’t change this setting.

How to install VMWare tools if the option is grayed out - new issue

Here’s what I tried (and failed)

  1. Ejecting the Windows ISO. I hoped this would free the drive and the virtual machine would let me install the tools.
  2. Disconnecting and reconnecting the virtual optical drive.
  3. Adding a second CD/DVD drive. It just kept giving me SATA0 errors.

None of this worked. This is when I searched the VMWare forums and found the solution on this thread.

How to install VMWare tools if the option is grayed out

1. Shut down the virtual machine.

2. Open VMWare Workstation Player and right-click on the VM. (Don’t start the VM)

3. Select the “Settings” option to edit the hardware settings.

4. Highlight the CD/Drive on the left side-bar under the Hardware tab and click on the remove button.

5. Repeat the above step to remove the Floppy Drive. (Optional, but this is what fixed it for me. Courtesy: AskUbuntu forums)

6. Click on the “Add button” and select “CD/DVD” Drive and select finish. The right pane should have now have the option “Use Physical Drive > Auto Detect” enabled. (Previously, it had the Windows ISO selected)

How to install VMWare tools if the option is grayed out - add cd dvd drive

7. Click on “OK” to close the window, and Start the VM as normal.

8. Once it has booted to the desktop, click on the menu at the top left corner and go to “Player > Manage > Install VMWare Tools”.

The option should no longer be greyed out. Click on it to install the VMWare Tools. You will also see a new tab at the bottom of the screen prompting you to install the tools.

How to install VMWare tools if the option is grayed out final

If this doesn’t work, you can try to manually download the VMWare Tools ISO, mount it in a virtual drive and install it. This isn’t limited to Windows 10 VMs, it should work on any VM be it Linux, macOS, or older versions of Windows.

How to use Sandboxie for browsing, downloading and installing programs

Sandboxie is a great tool to have in your computer’s security arsenal. For those unaware, it creates an isolated space (sandbox) on your hard drive that you may execute files in that cannot interact with the underlying system.

sandboxed program

The activity of the sandbox don’t affect Windows or your other programs/files in any way; what happens in Sandboxie stays in Sandboxie.

Sandboxie has changed hands twice I think, from the original developer to Invincea, who were in turn acquired by Sophos (and there are rumors that Sophos is up for sale as well). Recently Sophos announced that Sandboxie is now freeware, and are planning to make it open source.

We are not going to discuss that here, rather we’re going to look at the basic usage of the program. In other words, you will learn how to use Sandboxie for browsing securely, downloading files and recovering them, and installing/running programs inside the sandbox.

You don’t even need to familiarize yourself with the interface to use the program. In fact, I would recommend beginners skip the UI and use the tray icon.

Browsing securely

You can run any program that you have installed in Windows inside Sandboxie; this also works with portable apps and regular files (that open in other programs). Some programs may not work with Sandboxie if you try to install them directly inside the sandbox.

If you have installed Sandboxie, you will see the icon on the desktop, start menu and system tray. You can use any of these to run Sandboxed versions of your programs. The most commonly sandboxed program is the web browser. Right click on the system tray icon and select Default box > Run Web Browser. Your default browser, regardless of whether it is Firefox, Chrome, Edge or another will open like it always does.

You will notice that it has a yellow border around the edges of the window (when you mouse over to the edge). You can also see that the program’s window title is enclosed in two [#] [#] like this [#] Mozilla Firefox [#]. This indicates that the program is running inside Sandboxie. If you don’t see either the border or the hashes, it is not running in sandboxed mode.

You can use the sandboxed browser like you would normally. You can send emails, check social websites, visit tech sites like ours, and do pretty much anything that you would do in the unsandboxed version.

One of the main differences is that in case a malware infects the browser, it will be restricted within the sandbox. Say you visited a website with a malicious ad and it tried to infect your PC. While it will run, it cannot spread to the underlying system because of the sandbox. The sandbox limits the reach of tracking cookies and other unwanted things as well.

You can use the “Default box > Delete contents” option to delete the entire sandbox and start afresh. It is recommended to clean the sandbox once in a while to start with a fresh one.

Note: This is not the same as browsing anonymously, if you need that you should go with a VPN or use Tor.

You can even open links from any application (email, chat, etc) through a sandboxed browser, though you will need to tinker with the program’s settings to achieve this.

Downloading files and recovering them

Now let’s say you want to download an executable file or any other file in Sandboxie. It won’t be visible in your Downloads folder in Windows Explorer if you do so because the download is isolated in the sandbox.

How to use Sandboxie for downloading and recovering content

You need to recover the download, and to do so click on Default box > Quick Recovery. Use the recover to same folder option and the file should appear in your downloads folder (and ready to use in an un-sandboxed environment). You can run the file inside the sandbox however if you prefer that without the need to recover it first.

In case you don’t see anything to recover, you can also use the “Explore contents” option (which opens File Explorer) to manually browse your sandbox and recover the content. The latter is common if you use a custom download folder instead of Windows’ default one.

For e.g. I usually save my downloads to my external drive, so these won’t show up in Sandboxie’s Quick Recover. The contents will be available inside the C:SandboxAshwinDefaultBoxdrive folder in that case.

Installing and Running programs in Sandboxie

Why would you want to run a program inside Sandboxie? The main benefit is that you can run questionable programs and files inside the sandbox to avoid any damage or issues. It is even possible to run malicious programs inside the sandbox but it is usually better to use a virtual environment for that instead.

For portable applications, just extract them to a folder inside the DefaultBox’s drive folder and run them. To install a program inside Sandboxie’s protected environment, open File Explorer and right click any program’s installer.

How to use Sandboxie installing programs 2

Select the run sandboxed option and you should see the installer has a yellow border and hashes just like the browser. This indicates you’re installing the program inside Sandboxie. You will need to run the installed program manually from the Defaultbox folder.

How to use Sandboxie installing programs

Note: You can optionally grant the installer UAC rights if it is required.

Closing Words

I used Sandboxie for a long time until I switched to Kaspersky. Then I came to know they had some compatibility issues, so I ditched Sandboxie until recently when I bid adieu to Kaspersky. Since you now have literally nothing to lose with Sandboxie, I figured I might as well go over the basics for users who haven’t tried it out yet.

How to customize Spotify with Spicetify-cli themes

Spotify is one of the most popular music streaming services. If you use the desktop app on Windows, Linux or macOS, but dislike how it looks, you may be interested in customizing the client’s apperance.-

To do this, you need the free Spicetify-cli tool. It is an open source project that lets you change the looks of the official client quite a bit.

Spotify default theme before enabling Spicetify-cli

Spicetify-cli is the replacement of the now deprecated spicetify. The latter was a Rainmeter skin which was used for customizing the Spotify client; the former is a command-line tool.

How to install Spicetify-cli

Step 1: Download

Download the latest release from the official GitHub page and extract it to the C:Usersusernamespicetify-cli folder.


Open Powershell and run the following command (to download and install it)

Invoke-WebRequest “” | Invoke-Expression

Spicetify-cli install

Step 2: running the tool

You can now open Spicetify-cli from CMD or Powershell. Do it once by typing the command:


This will generate a config.INI file in a folder called .spicetify (in the user folder).

Step 3: backup the defaults

Backup the default settings and apply the default theme of Spicetify with the following command.

spicetify backup apply enable-devtool

Wait for it to finish and Spotify will restart with a light theme applied. This is the default Spicetify theme (It does have one bug the top right corner is still dark).

Spicetify-cli default theme light

To restore Spotify’s original theme use the restore command.

spicetify restore

How to customize Spotify with Spicetify-cli themes

Every theme used by the program uses the Color.ini file to configure the colors and the user.CSS to inject additional options. Confused? Don’t worry. For starters, let’s use some community created themes. Here are some great looking themes for Spicetify-cli.  Let’s install one of those as you don’t need to know a bit about CSS or editing ini files to use these.

  1. Download the theme of your choice, like the WintergatanBlueprint Theme. Click on it’s color.ini. You will see some lines of text. Create a new document using Notepad in a new folder inside C:UsersUSERNAME.spicetify.
  2. Copy the text of the Color.ini from the theme’s page into the document and hit save.
  3. Similarly, create a User.CSS file with the theme’s settings.

Now, we need to activate the theme. To do this, open a command window and type the command:

spicetify config current_theme = WintergatanBlueprint

Run the command: spicetify apply and wait for it to apply the new settings. Spotify will restart with the new theme.

How to customize Spotify with Spicetify-cli themes

You can edit the values manually to create your own themes easily.

How to customize elements in the Spotify UI with Spicetify-cli

Spicetify isn’t just about changing the colors of Spotify’s interface; you can modify the elements of the UI too. This is done by modding the Config.ini which is in the root of the .spicetify folder. Edits that you make here are universal across themes. Refer to the screenshot below to see what the default settings look like.

Spicetify-cli config.ini default

Tip: You can run the command “spicetify –help config” to view an explanation of every setting in the Config file.

There are 2 ways to edit these: The easy way is to just edit the config.ini in Notepad and running the spicetify apply command.

If you want to use the commandline method, the syntax is: spicetify config ELEMENT VALUE.  Where Element is the name of the interface’s element that you wish to modify, and value is a number (-1 or 0 or 1).  For example, say you want to disable the Home section. Run the following commands one at a time

spicetify config home -1

spicetify apply

How to customize elements in the Spotify UI with Spicetify-cli

Note: Some of these don’t seem to work, like the search_in_sidebar. It seems to be hardcoded to the top of the GUI.


Spicetify-cli comes with a few extensions that you can enable including Auto Skip Videos, Keyboard Shortcut, Shuffle+ and more. You’ll need to enable them from the config.ini. The filenames are as follows: autoSkipExplicit.js, djMode.js, keyboardShortcut.js, queueAll.js, shuffle+.js, trashbin.js.

Extensions should be separated by |, .e.g. Setting extensions = keyboardShortcut.js| shuffle+.js| will enable the 2 extensions.

I tested the tool mostly on Spotify 1.1.17, but it did work on older versions as well.

Note: Spicetify-cli does not disable ads in Spotify.

Spicetify is also available for Linux and macOS. Please refer to the official website for installation instructions.

Back to Basics: How to block Windows programs from accessing the internet

Today, in our Windows 10 beginner’s guide series, we’ll be looking at how to block Windows programs from accessing the internet.

Tip: check out some of the previous parts of the series, e.g. on changing default save locations or configuring programs to start on shutdown.

While it may work sometimes to cut the Internet connection, e.g. when installing Windows, it is usually necessary to use finer controls when it comes to blocking programs from communication with Internet servers.

How to block Windows programs from accessing the internet - Firewall step 2

The Windows operating system comes with a firewall that you may use for the purpose. While you may get a better experience when using third-party tools like like Windows Firewall Control, the built-in firewall is all that is needed to block programs from going online.

Before we show you how to do it, we’d like to discuss why you may want to block the Internet connectivity of certain programs.

Why would you want to do this?

Privacy is a core reason. We have seen applications phoning home, when they shouldn’t be (I’m looking at you CCleaner).  Programs may transfer data about your computer or Internet usage, your PC’s hardware, or other information, even files, to Internet servers.

Blocking internet access for programs is also a good way to prevent automatic updates. Maybe you want a program to stay on a specific version, e.g. uTorrent on a “clean” version or a version that comes without changes that you did not like, e.g. Bandizip’s upcoming changes that introduce ads in the free version.

Other reasons may include preserving data if your connection is capped or making sure that other applications get to use the full bandwidth.

How to block Windows programs from accessing the internet

Step 1: Open the Control Panel

How to block Windows programs from accessing the internet - Control Panel

Open the Control Panel and click on the “Windows Defender Firewall”. If you have troubles locating the Control Panel use the shortcut Windows-Pause to open it, select Control Panel Home, make sure small icons are selected, and start Windows Defender Firewall.

Tip: you may also use our guide on opening Windows Control Panel applets directly.

How to block Windows programs from accessing the internet - Firewall step 1

Select Advanced Settings from the side-panel on the left.

Step 2: Creating rules

How to block Windows programs from accessing the internet - Firewall step 3

We are going to create a new rule for the Firewall. So, we’ll need to select Outbond Rules from the left panel. Click on the “New rule” option on the right side of the screen.

An Outbound rule wizard window should pop up and it will have the “Program” option selected. Just click on Next to proceed.

Click on the browse button under the “This program path” box and an Explorer window should pop-up. You may also paste the path of the executable file (the program that you want to block) directly if you have it at hand.

How to block Windows programs from accessing the internet - Firewall step 4

Navigate to the folder which contains the executable (.EXE) of the program that you wish to block internet access for. Select the .EXE, and click on Open to add it to the Firewall.

You’ll be back on the Outbound rule wizard window, click on Next. Ensure that the “Block the connection” option is selected and click Next.

How to block Windows programs from accessing the internet - Firewall step 5

You now have to choose which networks it should be blocked on, Domain, Private and Public. If you are unsure, leave all three options checked and click on the next button.

How to block Windows programs from accessing the internet - Firewall step 6

Give the rule a name and add a description if you want (it is optional). I recommend using the program’s name for the rule’s name so you can identify it easily. Click on Finish, and you’re done.

How to block Windows programs from accessing the internet - Firewall step 7

Note: The description section can be left empty, or you could type something like “network not needed for usage, last known good version, or something similar”.

Repeat the process for every program that you wish to block from accessing the internet.

Tip: Programs like Windows Firewall Control display options to you when they notice Internet connections by programs for which no rules exist. They make this a bit easier as it just takes a click to block or allow connectivity.

Some programs may display news or ads, which are delivered from their own servers or from ad servers. In case you have an application which does something like that, you may want to create a Inbound rule using the steps that we have outlined in this article.

This method should work in Windows 7 and Windows 8 as well.

Back to Basics: How to change the default save location in Windows 10

Continuing with our beginner friendly back to basics guides, this time we show you how to change default save locations in Windows 10.

The operating system saves all documents, pictures, music etc to the drive Windows is installed on by default: this has always been the case in prior versions of the OS as well.

While that is the desired location for many users, some may prefer different locations, e.g. to store files on another partition or hard drive that has more space.

Tip: check out other parts of the series such as Windows Shutdown Autostart Explained, our Registry backup primer, our this part of the network troubleshooting series.

How to change the default save location in Windows 10

Microsoft implemented functionality in the Settings application of the Windows 10 operating system that allows users to change save locations in a simple and straightforward manner. It just takes a few clicks to do it.

Previously, you had only a couple of options, e.g. to use symbolic links / NTFs junctions.

Why would do you want to do this? Storage space can be an issue for some users. For example, I have a 120GB SSD in my computer and Windows 10 is installed on it along with a few programs. It gets accumulated with media, documents, etc, fairly quickly. This is a big deal, because it not only takes up precious disk space, but it also becomes a chore to move the data manually from time to time.

How to change the default save location in Windows 10

  1. Open the Settings app.
  2. Click on System and then on “Storage” from the side-bar on the left.
  3. Scroll down to the bottom of the page, where it says “More Storage Settings”.
  4. Click on the text that reads “Change where new content is saved”.

You are taken to a new screen which displays the default save locations for six different types of data: Apps, Documents, Music, Photos and Videos, Movies and TV Shows, and Maps.

Each of these options is set to “This PC” by default. To change the default save location click on the menu next to a data type and pick one of the available locations from the menu that opens; Windows 10 lists all partitions that are available on the computer.

How to change the default save location in Windows 10 - choose a drive

How to change the default save location in Windows 10 - apply

If you want to change the save location of Apps, simply click the button next to the icon and select a different drive. Click on the apply button which appears. You will see a progress cursor, wait for a few seconds and it should be done.  You will have to repeat this for each of the 6 options if you want to change the save location for each of the data types.

Once you have done this, Windows 10 will save the data to the selected partition. You may have to re-open existing applications for the change to be reflected though.

Note: Windows will still create its Documents folder for each of the selected drives. It will be created in the following format: “UsernameContent Type”. For e.g. selecting D: as the new location for pictures on my computer created the folder in D:AshwinPictures. It’s too bad that you can’t pick a custom folder for the saved data, but this option should be fine for most users.

Windows 10 allows you to pick different partitions for different categories. Continuing with the previous example, you could select a different drive for Documents, say E:. You could set Music to be saved on F: and so on. It also lets you select other hard drives installed on the computer. So, you can use them for saving content as well.

But what about USB hard drives? Can I use those? If you have an external drive connected to the computer, you will see it listed as well. But I’d really only recommend using it for the save location, if the drive will be permanently connected to the computer.

Closing Words

Moving save locations to a different partition or drive is a welcome feature but it is a bit unfortunate that the folder structure itself cannot be changed at all. Windows 10 replicates the default storage path on the new partition and there is no option to change that.

Other than that, it is a good option for users who run out of space on their primary partition regularly.

Extract images and other content from Office documents with this simple trick

Here is a quick tip to extract images and other content from Microsoft Office, LibreOffice, or OpenOffice documents among others. While it is possible to save images embedded in Office documents in Office, e.g. by right-clicking on an image and selecting the save option from the context menu, it becomes a burden if you need to save multiple images from a document or extract images or other content regularly.

I reviewed a software program in 2011 called Office Image Extraction Wizard which automated the process but it has not been updated for a while.

The main idea behind the trick is simple: the default document formats of Office suites, e.g. docx, xlsx, or odt, are zipped XML-based files and that means that they can be extracted using archive software such as Bandizip, 7-Zip and other programs.

Most extraction programs don’t support the default Office file formats by default on the other hand which makes it necessary to rename the file extension of the files to zip before running the extraction.

Office software does not need to be installed on the system for this to work and it is also supported on all platforms and not just Windows. All you need is the document in question and an archive software.

explorer show file extensions

Here is how that is done in Windows:

  1. If you see all file extensions in Explorer already skip to step 3. The default file explorer hides the file extension for known file types by default which interferes with the renaming of files.
  2. Open Explorer and select View  and make sure that “file name extensions” is checked under Show/hide there. You should see file extensions, e.g. .odt, .zip and others in Explorer.
  3. Right-click on the document that you want to extract and select rename from the context menu.
  4. Leave the file name but replace the file extension with .zip. The file test.odt would show up as afterward.
  5. Right-click again on the file (now with zip extension) and select the extract option. Most archive programs add context menu options.
  6. Wait for the extraction to complete.

You may now open the extracted zip archive and explore its content. The folder structure may differ depending on the document that you have extracted.

extracted office document

Extracted ODT Office documents may have a Pictures folder in which all embedded images are stored in; Word documents a word folder with media and fonts subfolders.

One of the advantages of the method is that you get access to all embedded media files and fonts right away which speeds up the process significantly. The process may also be useful if the document is corrupt and won’t open anymore in the Office program. You may still be able to extract content from it.

Where are desktop backgrounds (wallpapers) stored in Windows 10?

The Windows 10 operating system comes with a set of wallpapers and the ability to refresh wallpapers regularly from a pool of images. The following guide provides users of Windows 10 with instructions on finding these wallpapers on the local system.

Let’s say you want to use them on your other devices (smartphone, TV, Xbox One or PS4), or want to make a background image of the past the permanent background on the Windows 10 device. You need to know where to find these wallpapers, and that is the guide for that.

Even if you are an advanced user, there is a chance you may not know about it. You won’t find them in the Pictures folder, that’s for sure.

Where are desktop backgrounds (wallpapers) stored in Windows 10?

Where are desktop backgrounds (wallpapers) stored in Windows 10

Open File Explorer and navigate to the following folder or copy the path and jump to it directly: C:WindowsWeb.

This is not really an obvious place to find wallpapers, is it? One would think the folder is probably something related to the internet. The Web folder houses 3 sub-folders which are called: 4K, Screen, and Wallpaper. Surprisingly, all three folders have wallpapers and different ones at that.

The default Windows 10 wallpaper, which is the one with the light beams and the Windows logo, can be found inside the “C:WindowsWeb4KWallpaperWindows” folder. The name is once again a bit misleading because the 4K folder also happens to contain the wallpaper in several other screen resolutions like 1024 x 768, 1366 x 768, 1920 x 1200, 2560 x 1600 and 3840 x 2160 pixels.

You may have noticed that the aspect ratios of the wallpaper differs, so you may want to select the one that matches your device’s display resolution. If it doesn’t match the screen size, you can always resize the wallpaper using a tool such as Irfan View, Fast Stone Photo Resizer, Flexxi, etc.

The second folder “Screen” contains photos which the operating system uses for its lock screen and log-on screen. That is probably why the folder is named “screen”.

desktop backgrounds location in Windows 10

The Wallpaper folder has a number of sub-folders of its own: Windows and Windows 10, and then a number of folders based on past usage. You may have folders like landscapes, architecture, or flowers there.

If you are a fan of macro photography and nature, you will probably dig what’s in the Flowers folder. The Windows folder has one wallpaper, and that is the 1920 x 1200 pixels version of the default wallpaper. The Windows 10 folder on the other hand, contains some nice walls related to outdoor activities.


Another source of wallpapers are themes. These themes, you may install hundreds of them from the Microsoft Store, are not placed in the Web folder when you install them. Instead, they are placed in the user folder.

Use the following path as a starting point in File Explorer to browse the installed themes and the backgrounds they come with: %localappdata%MicrosoftWindowsThemes

Closing Words

Now that you know where to find the wallpapers, you can copy them to your other devices or maybe use it on a multi-monitor setup too. You can drop your own wallpapers in the folders in case you want to switch to a different one quickly from the Personalization section in the Settings app.

I have seen fan edited versions of the default wallpaper which look stunning. Some have different colors for the background while maintaining the art style, maybe you can create something similar with it if you are a graphics designer.

Which among the default Windows 10 wallpapers is your favorite?

How to import tabs from Chrome to Firefox and vice versa

So, you have decided to switch from Chrome to Firefox, or maybe it’s the other way around. The problem is you have a lot of tabs opened, and you can’t abandon the session. Or, you use both web browsers regularly and want to push tabs from one browser to the other; this may also be useful for developers who need to test their sites in different browsers.

What do you do? Manually copy and paste each URL from one browser to the other? That could take a long while depending on the number of tabs that you want to push to the other browser.

The browser extension OneTab offers a solution that improves the process especially if you need to push multiple tabs to the other browser.

Note: Please be advised that the following process will close all of your tabs and save the session to a list. But don’t worry, you can restore the entire session just as easily.

1. Once you have installed the add-on, you should see its icon in the browser’s toolbar.

2. Click on the button to open OneTab (this closes all open tabs)

3. Select the “Export/Import URLs” option on the right side of the page.

4. You should see an Import/Export tab that has a list of all the tabs that you had opened. It has the URL and web page title for each tab.

5. Copy this list to the clipboard.

6. Open Firefox and repeat steps 2 and 3.

7. Now you should be on the Import/Export tab. Paste the list of tabs from step 5 in the Import text field.

8. Click on the import button.

OneTab should open a new tab which displays the tabs that you just imported. Click on the “Restore all” option, and the add-on should open all the tabs at once. You can also choose to restore only the ones that you want, by clicking on the tab titles individually.

That’s it. How simple was that? The process works the other way too, i.e., if you want to export tabs from Firefox to Chrome.

Note that it is theoretically also possible to send the list of exported URLs to a contact. May be useful to share research or let someone pick off where you stopped.

Another use for this method: Backup your sessions

I use this method for a different purpose. Over the course of a week or two, I accumulate several dozens of sites in tabs that I find interesting or have opened for future research purposes.

When I don’t have the time to go through the list just yet but want to start fresh because the browser’s tab bar gets convoluted, I use the extension to save the entire list of open sites in a text document.

You can use the import option to restore the tabs anytime you want to. You can even backup your session, clear the browser’s data and cookies and restore the tabs right back. This has been helpful for me quite a few times over the past few years.

Note: OneTab hasn’t been updated for a while on Chrome, but it still works perfectly. The Firefox version is updated frequently. There is an open source alternative for OneTab, called better-onetab, which I haven’t used much since it was pulled and re-released by the developer.

This post was inspired by something I saw on reddit’s Firefox sub yesterday. It was an interesting post, but they used the developer console to move tabs from Chrome to Firefox and it also involved using two different extensions which made it a slightly more complex method.

How to whiteout text in PDFs using DocHub and Google Docs

Filling up a PDF form is pretty easy. You fire up a PDF editor application, use the text tool in it and type away.

How to whiteout text in PDFs using DocHub and Google Docs
Editing a PDF which already has text in it? It’s not that easy.

Say for example, you have an application form which has a few text fields but instead of blank boxes to type in, there is already text in some of the fields like “Write in CAPITAL letters”, “Include your State”, etc.

I know this is a rare example, and your use case scenario might be a lot different. Editing such forms can be a lot more difficult. Why? Because PDFs are meant to be finalized versions of documents, hence you can’t delete text from them like you would do in Microsoft Word or LibreOffice Writer.

The hard way

You could try taking a screenshot of the PDF and use an image editor to erase the text. Then you could print and scan the edited version to create a new PDF. Use a PDF editor to write what you wanted to in it. That’s a lot of work. And what if you don’t have a printer or a scanner?

The easy way

There are a few ways to do this including using paid applications like Adobe Acrobat. Inkscape is a free option which supports PDF editing and it could work well (depends on the PDFs content).

If you have Microsoft Office, you could try using Word to edit PDFs. LibreOffice supports editing PDF documents as well. During my tests, all three programs rendered parts of a test document useless (for e.g. check boxes were missing or distorted, images/logos were blurred etc).

Even if I could erase text using these applications, I would not be able to use the document because the programs had modified other parts of the PDF. Offline free PDF editors that I tried didn’t have a whiteout or eraser option either.

There are quite a few online services that let you edit PDFs. And one of the most popular ones is Google Docs.

How to whiteout text in PDFs using DocHub and Google Docs

1. Upload the PDF to your Google Drive.

2. Double-click on it to preview it.

3. There is an “Open With” option at the top of the screen. Click on it and select “DocHub”. (This is a third-party service but is trusted by Google).

4. You will be prompted to grant DocHub permission to access your Google Drive. It needs this to read/write your PDFs. Once you allow this option, you can use the DocHub website directly in the future (as long as you’re signed in to your Google account).

5. The PDF should load in DocHub and you will see a toolbar at the top of the screen.

6. Select the Whiteout tool (eraser icon).

7. Draw a box over the text that you wish to delete. And it will be deleted.

8. Save the PDF and it’s ready for use.

Edited PDF DocHub

In case of our application form example, this method can be used to make the text field appear blank. After which you can use the text tool in DocHub or any PDF editor to fill the form.

There you go, a free cross-platform to whiteout text in PDFs. All you need is a web browser, and a PDF, obviously you need one.

Closing Words

Online services may not work in all situations as you may not want to upload confidential documents to an online service. If the PDF document is generic however, it is a valid option that should work in many contexts.

Now You: Which tool or service do you use for editing PDFs?
