How to increase partition space by extending in Windows 10 Wed, 14 Aug 2019 04:30:15 +0000 // It may so happen that you might need to increase your partition size of an existing drive. One option is where you get a new hard disk, but if you have enough space on the primary drive, you can increase/decrease the size to create more space. In this post, we will suggest how to increase Partition space or hard disk space by extending feature in Windows 10

How to increase partition space by extending in Windows 10

I will start with an example. Let’s assume you have 20 GB free in D drive and 10 Gb free in another, but the total occupied data is only 10 Gb.  It means you can eventually transfer data from one drive to another using some File Copy Tool like Robo Copy and add the rest of the space to drive where you need it most.

If you have a brand new machine where you don’t have any data on your hard drive, delete and recreate partitions instead of messing with the Extend Partitions fundamentals. That would be a lot easier.

That said, let’s understand a few aspects you should know even though we are just talking about increasing partition size.

  • What is Shrinking of Partitions?
  • What is Extending of Partitions?
  • How to extend the size of the existing partition

What is Shrinking of Partitions?

You can reduce the amount of space in any hard drive so you can squeeze out free space. But before doing so, you will need to defragment your hard disk. It is required for best results and is something like cleaning up room to put things at their place, so the room has more space.

To perform regular defragmentation, you can use Windows De-fragment Scheduler or Tools like MyDefrag or Defraggler.

What is Extending of Partitions?

Extending of partition is like using the free space to increase your room area. Technically you can extend a partition space by adding some free space. Remember its not merging of partitions. That is different.

How to increase the size of the existing Partition in Windows 10

Basic Requirement

  • You will need an admin account to complete the task.
  • You need to have Free Space to extend any partition.
  • Free Space section should be on the right of the partition you want to extend.

Extend Shrink Restriction

For the example below, I am calling the partition you want to expand as X.

Step 1: Understand the physical arrangement of your partition

Launch the Windows Disk Management tool by searching for partitions tool in the control panel. You can also type diskmgmt.msc in the Run prompt, and hit enter. The tool displays a list of connected hard drives and partitions. Total Size, free space, status, file system, etc. are listed.

Since we are merging, extending, etc., make sure that you understand how partitions are ordered. Imagine it like a stack of bread on top of each other except that you can pull it out and replace it.

Step 2: Manage Files and Plan your space

  • Find your exact requirement: How much space you want, existing partitions space, their free space, etc.
  • Start moving files from one partition to another so that you create free space which can be used by the partitions which need expansion.

Remember you can only extend a partition if there is a free space in the right.

Step 3: Create Free Space

Once all your files are moved, create free space if you don’t have from existing Partition or Volume. The free space is displayed with Green Color.

  1. Select a volume which is on the right of X and next to it.
  2. Right-click and click on Shrink Volume.
  3. Key in the amount of space you need to add to X.
  4. Once this is done, you will see Free Space on the right of X.

Shrink Volume in Windows

Step 4: Extending the Volume

  • Since you have free space, Right-click on X and Select Extend Volume.
  • Select which disk partitions you have listed in the screen and add them.
  • Next and you will see a summary and the partition will be merged with free space.

Extend Volume Wizard Windows

One thing I did not warn you as about backing up the data in the partition you plan to extend. Its not required most of the time as the data will be not lost at all. I had tried it with almost like 20 GB of data and nothing went off the disk.

However, if you are worried about data and even, we would suggest, Backup your data but then if you can spend time on backing data then creating free space is all hassle, just backup and recreate everything from fresh.

Also, there is a concept of Dynamic Disk which lets you extend partition space across disks, i.e., two or x number of the hard drive. It is handy as are not restricted by the physical location of your volume.  We will talk about it in upcoming posts.

As a summary, depending on how much data you have decided what suits you best.  Extending is a great option and use it when you get a chance.

Repair for Photo add multiple images

During the repair process, each of the images will be marked as repaired or advanced repair. The one with fixed can be exported out.  However, pictures marked with Advanced Repair means, additional processing is required. For each image, a thumbnail is also generated.

Stellar Photo Recovery Process

Advanced Repair for corrupted images

It is no trick, but smart processing. Here an image can be repaired using a sample image of similar type. We usually end up taking multiple pictures of the same scene. So if you have anything related, the software can use that as a template to fix corrupted images.

Advanced Photo Recovery

Click on the advanced repair, and click on Next. Select a similar image, and continue with the advanced recovery. The option works only for severely damaged JPEG files. Make sure the image is of the same format, was shot using the same device. The original photo remains untouched after the process is complete.

Overall Stellar Photo Repair tool looks great. It is simple, straightforward, and it works as expected. It should work with most of the corrupted photos unless it is severally damaged. Even for those, the software attempts to recover them by analyzing similar looking images.

How to disable Switch to Tab in Firefox and Chrome Mon, 12 Aug 2019 14:30:00 +0000 // Switch to Tab, is a feature in Firefox and Chrome which saves your time by switching to the already existing tab which matches the URL you type in the address bar, instead of reloading the page again. Though this feature handy, sometimes people do not want to switch, for example, I would rather open the URL once again and compare to the already loaded page to see the difference. In this post, we will share how you can disable Switch to Tab in Firefox and Chrome

disable Switch to Tab in Firefox and Chrome

How to disable Switch to Tab in Firefox and Chrome

1] Manually bypass

To temporary bypass switch to Tab, press Alt + Enter or Middle Mouse Click when you type in the URL. It will load the page in the tab instead of switching to the existing TAB.

Also, you can hold down the Alt or Shift key while an entry in the drop-down list is highlighted to disable “Switch to tab” and see the URL of all entries instead.

  • Alt + Enter opens the highlighted URL in a new tab.
  • Shift + Enter opens the highlighted URL in the current tab.
  • Cursor Right copies the highlighted URL to the location bar in case you want to edit it.

2] Disable switch in the configuration


  • Type about:config in the address bar, and hit the return key.
  • Locate the entry “Browser.urlbar.switchtabs.adoptintoactivewindow
  • Double click to disable it.


  • Type chrome://flags/#omnibox-tab-switch-suggestions in the address bar of Chrome and hit enter.
  • The description would say “Enable suggestions for switching to open tabs within the Omnibox. – Mac, Windows, Linux, Chrome OS”
  • Change from default to disable.

3] Using an Extension

If you want to use Switch to Tab feature but still want to open the same URL again, I would suggest you use Duplicate Tab(Firefox, Chrome). This add-on adds a Duplicate Tab menu when you right-click on a tab or on a link inside a webpage.

Duplicate Tab

Along with the duplication it also gives you option to merge, configure new tab to open right next to an existing tab, use mouse clicks and shortcuts and so on.

How to create fake speakers and microphone in Windows 10 Sun, 11 Aug 2019 14:30:50 +0000 // Sometimes you require to use audio of one program to be used by another application. For example, if your friends want to listen to music over messenger or Skype. The only option is to turn on your mic and play the music loud so he or she can listen to it. The problem here is the sound quality is not right, and it will also carry external noise. In this post, we will share software which can create fake speakers and fake microphone in Windows 10

How to create fake speakers and microphone in Windows 10

Virtual Audio Cable Software allows you to create virtual speakers and mic. Even though they are programs, they are identified as hardware by any other program. That includes Windows Media Player or any messenger service like Skype or Yahoo Messenger. So now you can do two things:

  • Play music on your Windows Media Player or VLAN and stream it to Virtual Speakers
  • Stream to a Virtual Speaker and Record it using Audacity.

fake speakers microphone Windows

How to setup Virtual Audio Cable

  • Download it from here and Install it with admin privilege.
  • Then launch the Control Panel of the application.
  • By default, it will create one cable for you. Check the box which says mic under-connected Source Lines.
  • Leave the rest of the settings to default.

Virtual Audio Cable Settings

Here is an example using Windows Media Player and Yahoo messenger. It works almost the same way for any other software. You need to figure out to configure speaker and microphone settings for those apps.

Play music on your Windows Media Player and stream it to messenger

  • Launch Windows Media Player. Press Alt and Go to Tools > Options >Devices > Speakers
  • Change the speaker choice to Line 1 (Virtual Audio Cable)
  • Keep a song ready to play.
  • Now Launch Yahoo Messenger and Go to Preferences > Video and Voice
  • In Microphone select Mic 1 (Virtual Audio Cable).

Yahoo Messenger and WMP Audio Settings
Now when you play a piece of music from Windows Media Player, it is streamed out using Line 1 Audio and captured by Mic 1 Audio to the messenger. Since this is virtual and not a physical mic, it will be noise-free.

Stream what your friend is saying to a Virtual Speaker and Record it using Audacity

This method is useful if you want to record what your friend is speaking. Keep the messenger settings the same, but in Audacity, you need to change PlayBack Device to preference to Line 1 (Virtual Audio Cable). Make sure to close Windows Media Player else it will mix both the sounds.

So here is how it works. The audio from your friend is streamed to Line 1, which is a virtual speaker. Audacity records the sound from this virtual speaker. It is the same as if you were recording online audio using your real speakers as your output and mic as input. The difference is you will get better quality here.

Audacity Recording Preferences

What else can you do?

  • Play Music from two media players and use two different virtual speakers and then record it.
  • Record Calls on Skype, Yahoo or similar instant messenger  programs
  • If you have an encoding software, stream directly from virtual speakers to it.

How does it work?

VAC contains Windows WDM/KS virtual device driver that creates virtual audio devices. This driver is a kernel-mode module and needs to be installed with administrator rights.

Being a WDM/KS filter, VAC represents a lowest-level audio layer in Windows. It can be effectively used by any upper-level layer (KS-aware applications, WASAPI, MME or DirectSound subsystems, ASIOwrappers and so on).

Is it Free?

Yes and No both.  The free version has a limitation on several speakers you can create, and it emits a female voice after every few seconds. Now if you are using it for personal use, you can ignore it but if you are using it professional work you can buy it.

What About Video?

The software only supports audio, but if you want to stream a video to your webcam or create virtual webcam that can be used by messenger program, I will suggest you take a look at the list of Webcam Tools we talked about.


This application Works on Windows 10, Windows 8.1, Windows 7, Vista, and XP. 32 and 64 bit systems. You can download both free and trial versions.

How to Restart Firefox in Safe Mode or Refresh Firefox Sat, 10 Aug 2019 05:30:28 +0000 // Using a browser with extensions is very common. When you have multiple addons, and your Firefox is not working as expected, it is best to disable all the addons. In this post, we will share how you can restart the browser with all Addons disabled. There are two options. One is you can choose to restart Firefox in Safe mode, or you can refresh Firefox to start from scratch.

Restart Firefox with addons disabled

The switch is oddly placed under Help menu and right under Submit Feedback. Did you notice?

How to Restart Firefox in Safe Mode or Refresh Firefox

  • Launch Firefox and click on the hamburger menu on the top right
  • Then click on Help.
  • Look for the menu which says Restart with Add-ons disabled.
  • Click on confirm, and the browser will restart in its vanilla state.

When you choose to restart, Firefox will pop another window where it will offer you two options:

1] Start Firefox in Safe Mode

It is a particular mode of Firefox that can be used to troubleshoot issues. Your add-ons and custom settings will be temporarily disabled. And Firefox features may not perform as they currently do.

There is one small problem there is no option provided to enable all the add ons with the same switch. You will need to enable all of them one by one.

In previous versions, Firefox used to give more granular options. Instead of Disabling addons, you could choose to reset.

  • Reset Toolbars and Controls
  • Delete All Bookmarks
  • Reset user preferences on Firefox Defaults
  • Restore to the default search engine.


Safe Mode Firefox Refresh

These are not available anymore.

2] Refresh Firefox

If you’re having problems with Firefox, refreshing it can help. When you refresh Firefox, it can fix many issues by restoring Firefox to its default state. It will save your essential information like bookmarks, passwords, and open tabs.

Since Firefox will revert to its original state, your configurations and customizations, including extensions, extension data, and about: config preference configurations are removed.

Firefox will save these items:

  • Bookmarks
  • Browsing and download history
  • Passwords
  • Open windows and tabs
  • Cookies
  • Webform auto-fill information
  • Personal dictionary

Firefox Refresh will remove items and settings

  • Extensions and themes
  • Website permissions
  • Modified preferences
  • Added search engines
  • DOM storage
  • Security certificate and device settings
  • Download actions
  • Toolbar customizations
  • User styles (chrome subfolder containing userChrome and/or user content CSS files, if previously created.)

How to Restart Firefox, i.e. Plain Simple Restart :

If you want to restart Firefox without manually closing and then relaunching, Quick Restart is an excellent Firefox Add-on. In case this doesn’t work on your Firefox, learn how to install it here.

Efficiently Search Browsing History in Firefox with these Extensions Fri, 09 Aug 2019 04:30:45 +0000 // Many a time it is necessary to look back at the history of websites you browsed. Useful either to retrieve forgotten website URL or for the accidentally closed tabs. What is even more important for many is to find out the sequence of websites that were visited. Below is the list of Extensions and Add-ons which will help you quickly access, search browsing history in Firefox using complex queries or deleted them when not required.

Efficiently Search Browsing History in Firefox with these Extensions

  1. Backtrack Tab History
  2. Form History Control
  3. Tab Session Manager
  4. From Where to Where
  5. Firefox Menu Creator

1] Backtrack Tab History

When you open link in a new tab and accidentally close the parent tab, all your history for the parent tab is lost. Let’s say you have browsed through 5 websites to come to existing link and you opened one link in a new tab, this new tab does not have a history associated as its new but when you accidentally close the parent tab it’s all lost.

Backtrack Tab History associates the history of the new tab with the parent tab from where it was opened. So if you plan or accidentally close the parent tab, you can still browse back to all the pages through which you came here.


2] Form History Control

This is a powerful tool which gives you complete control over your history. You can :

  • Search your History using complex query using Regular Expression.
  • The Query supports Field Name, Value, No of times used, Match Case, Dates, etc.
  • Direct option to delete history which has the same name or value.
  • Create Cleanup Criteria for quick deletion.
  • You can also have protection criteria for histories you never want to delete.
  • Allows you to add a new entry to create a fake history.
  • Export and Import History.

History Search Form


3] Tab Session Manager

This addon makes it easy for you to find all the history for a particular tab only. For example, let’s say are browsing through Google News different section and articles inside it. All the pages you visited can be accessed easily.

Tab Session Manager

Save and restore the state of windows and tabs. It also supports automatic saving.

  • Save and restore windows and tabs
  • Manage sessions with name and tags
  • Autosave when the window is closed and at regular intervals
  • Import and export sessions
  • Compatibility with Chrome extension


4] From Where to Where

This extension is a little bit complex but powerful. So I will suggest this for power users. It displays history results for a keyword in tree fashion i.e. All pages you visited and pages you visited from those pages. What is more useful is its ability to bookmark them separately so you can revisit them easily.

Browsing History of FirefoxDownload

5] Firefox Menu Creator (History Feature)

Using Firefox Menu Creator you can get one-click access to all your history either by adding a new button near to your browser address bar or the Firefox Menu. Instead of the dropdown, it can be listed as an open list so you can see and access the latest one right there. Read more about this.

Firefox Reconfigured Menu

All these extensions will help you get back the pages you have already visited, have just closed. It saves a lot of time.

Smart Firefox Addons for improving File Download experience Tue, 06 Aug 2019 04:30:56 +0000 // The download manager in Firefox has evolved with time bringing in many features but still many of us, use download managers like Download manager Tweakle. Now if you are not interested in using those complex download managers, here is a list of addons which enhance your file download experience by adding small features in it.

Smart Firefox Addons for improving File Download experience

1] Display File Size before download starts

File size of any download is only displayed when you start downloading, and sometimes it is even not displayed. Show file size adds the size display feature in the window that popups before the actual download start.

File Size Display in Download

2] Avoid Duplicate Downloads

How many times has it happened that you start downloading the same file again? For me, it often occurs especially files downloaded from Emails, etc. While it might not matter much for smaller file size, but for anything more significant, some of us needs it to be taken care.

DLTracker or Download Tracker checks if the file is already available, which is found by matching the name and size and warn you if it is already there.

Avoid Duplicate downloads in Firefox

It definitively saves a lot of time and bandwidth in a small amount.

3] Let browser display file if supported

Many a time you don’t want to download a file but instead take a look or preview it. However, for technical reasons, Firefox may be forced to download a file (Content-Disposition HTTP header by the webserver from where the data is getting downloaded. In fact, because of the Content-Disposition HTTP header, the user default option can be overridden.

InlineDispostion handles this situation by not letting servers forced to download and instead make users option be honored. So if you have set to view individual files right in the browser, it happens that way!!

4] Preserve download date

Most of the files that are downloaded are modified after they are downloaded. It is a common thing for documents, images, etc. It means you will not be able to figure out when a file was downloaded because the file modification time has changed.

Preserver Download Modification Timestamp takes care of this by preserving the time which is sent by the server and also keeps track of download source and destination.

5] Keep track of the origin of the download

Many a time you need to figure out from a where a file was download, especially after you had deleted the file. No browser keeps a record of it, so if you need to track, here is a recommendation.

Saved from URL is a Windows software which can track all the details about the download. It tracks download URL, download Filename (with full path), Referrer, MIME Type, File Size, Start/End Time, Download Duration, and Average Download Speed.

I feel these addons should get into a core feature of Firefox and many other modern browsers. Though the download managers are getting smarter, these features haven’t made it into the browsers yet. So till then enjoy the addons!!
