Disk Space has always been a luxury be it the old days of DOS where everything was stored on a floppy disk or our modern times where we find it difficult to store our music libraries on a single drive. Depending on your current system configuration you could easily run out of space as you keep using your system.

This space could be used for temporary files, paging files, old Windows, large archives, download files, and more. The best way to free up some space tends to be to delete the largest files on your system, but finding these files can prove to be a challenge. In such cases, you can use our guide below to identify and delete the largest files on your system. Let’s get started.

Method #03: Free up space using other options under Storage settings

Click on ‘View Desktop/Music/Documents/Videos’ and you will be redirected to your desktop.

Click on ‘Sort’ at the top.

Click on ‘More’.

Selected files should now be deleted from your selected folder. 

Method #04: Using WizDirStat

WizDirStat is a popular open-source utility often used to generate a graphical representation of your local storage space in a user-friendly manner. This makes it easier to identify large chunks of your disk space occupied by a single file, folder, or archive, which in turn will make it easier for you to free up some space on your PC. Use the guide below to identify what is taking up space on your Windows 11 PC. 

Download and install WinDirStat on your PC using the link above. Once installed, launch the app.

 

Now select one of the options that best suits your needs. If you only have a single drive installed on your system with a single partition, then you can skip this step. Click on ‘Ok’ once you are done. 

  • All Local Drives: This will make WinDirStat analyze all your disks and display their data graphically. 
  • Individual Drives: Select one of your installed drives to be analyzed for disk space usage. You can select this option and then select the drive you wish to use. 

Your drives will now be analyzed and you can track the progress for the same at the bottom of the window. 

Once analyzed, a color-coded graphical representation of the disk space usage on the selected drive(s) will be shown on your screen. Simply click on the largest chunks to identify the largest files. 

Press Del on your keyboard to delete the file. This will send it to your recycle bin and you can decide its fate when reviewing your recycle bin items. Alternatively, you can use Shift + Del to permanently delete the item from your system. 

And that’s it! You can repeat the last steps to delete more of the largest files from your system. 

Method #05: Using Windows Search to delete large files

Windows Search can also help you identify the larges files on your system in Windows 11. However, this is a hit and miss for now with the new file explorer, and in case the method fails to work for you, then you will need to temporarily switch back to the Windows 10 file explorer. Don’t worry, once you have identified and found the largest files, you can revert the changes and get back to the new Windows 11 file explorer. Use the guides below to get started.  

5.1 Search for large files

We will now search for large files based on your criteria.

Press Windows + E on your keyboard to open the file explorer and click on the search box in the top right corner. Search for the following term.

size:gigantic

The results will now be filtered and files larger than 4GB will now be displayed on your screen. Select the unnecessary files that you do not need on your PC and simply delete them to free up some space. If you wish to use a smaller minimum file size, then replace ‘gigantic’ with one of the terms below depending on the size you prefer. 

  • Large: Files between 128MB and 1GB
  • Huge: Files between 1GB to 4GB
  • Medium: Files between 1MB to 128MB

And that’s it! You can use Windows Search this way to filter files by their size and find the largest ones currently on your PC. 

Note: In case your PC indexes and shows system files as well then we recommend you double check files before deleting them to avoid deleting any vital system files from your system. 

You will now have found large files on your PC using Windows Search.

5.2 If the search term does not work for you

If typing in ‘size:gigantic’ does not work for you, then you will need to switch to the old file explorer from Windows 10. Use the guide below to get you started. Once you switch back to the old file explorer, use the guide above to search for large files. Once found, use the subsequent guide below to get the new Windows 11 file explorer back on your system. 

Switch to the old file explorer

Press Windows + S on your keyboard and search for ‘Regedit’. Click and launch the app from your search results. 

Navigate to the following directory or copy-paste the address below in your address bar. 

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Shell Extensions

Click on the folder named ‘Blocked’. 

Right-click on an empty area on your right, select ‘New’ and then click on ‘DWORD (32-bit) value’. 

Enter the following name and press Enter on your keyboard. We recommend you copy-paste the same to avoid any naming errors. 

{e2bf9676-5f8f-435c-97eb-11607a5bedf7}

Close the registry editor and press Ctrl + Shift + Esc to open the Task Manager. Switch to the ‘Details’ tab.

 

Click on ‘Explorer.exe’ and hit Del on your keyboard. 

Click on ‘End process’ to confirm your choice. 

Click on ‘File’ and select ‘Run new task’.

 

Enter the following in the text box and click on ‘Ok’. 

explorer.exe

Windows File Explorer will now restart on your system and it should be reverted to the Windows 10 File Explorer. You can open a random folder to check the same. Confirm that you have gone back to the old file explorer and use the guide below to find large files on your system.

Switch to the new file explorer

We can now revert to the old file explorer. Follow the guide below to get you started. 

Press Windows + S on your keyboard and search for Regedit. Click and launch the app once it shows up in your search results. 

Navigate to the following path below or copy-paste it in your address bar.

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Shell Extensions

Simply click on the DWORD (32-bit) value we had created earlier and hit Del on your keyboard. Click on ‘Yes’ to confirm your choice.

Press Ctrl + Shift + Esc on your keyboard and switch to the ‘Details’ tab. 

Click on ‘explorer.exe’ and hit Del on your keyboard. 

Click on ‘End process’. 

Click on ‘File’ and select ‘Run new task’. 

Type in ‘explorer.exe’ and hit Enter on your keyboard. 

You can close the task manager and registry editor on your PC now. 

And that’s it! You will now have gone back to the new File Explorer on Windows 11. 

Method #06: Using CMD (command prompt)

CMD can also help you find large files on your system. Use the guide below to get you started. 

Press Windows + E on your keyboard and navigate to a location where you wish to search for large files and click on the address bar at the top.

 

Type in CMD and press Enter on your keyboard. 

CMD will now be launched in the particular folder. Type in the following command and replace ‘PATH’ with the path we copied to your clipboard.

forfiles /S /M * /C “cmd /c if @fsize GEQ 1073741824 echo @path > largefiles.txt

The above command will look for files larger than 1GB on your PC. If you wish to define a larger minimum size, then replace ‘1073741824’ with one of the following options below.

  • 2GB: 2147483648
  • 5GB: 5368709120
  • 10GB: 10737418240

Execute the command with your desired variables and a text file will be created in the same location with a list of all the large files found on your system based on your criteria. You will also find the path for each file on your local storage in the text file.

You can use this list to identify the largest files in the current location and then delete them at your discretion to free up some disk space on your system.

Method #07: Using PowerShell

You can also find large files on your system using PowerShell. Just like the command for CMD, PowerShell will scour your local files based on a minimum size and display all the files larger than it. Use the guide below to get you started. 

Press Windows + E on your keyboard and navigate to the location where you wish to look for large files. Click on the address bar at the top and type in ‘PowerShell’. Press Enter on your keyboard once you are done. 

Copy-paste the command below in the PowerShell window and press Enter on your keyboard. 

gci -r| sort -descending -property length | select -first 10 name, length

You will now get a list of the top 10 largest files currently taking the most disk space on your system. If you wish to view the top 20 files, then replace ‘select-first 10’ with ‘select-first 20’. 

PowerShell will now find and display the 20 largest files on your system along with their size. The file size will be in bytes which can make it a bit difficult to judge the size of files in terms of gigabytes. 

And that’s it! You will now have found the largest files on your PC using PowerShell in Windows 11. 

Method #08: Using SpaceSniffer

Space Sniffer is another popular third-party utility used to analyze disk space usage on Windows 11. Space sniffer can help you identify large files using huge amounts of space on your system. You can also find hidden files taking huge disk space on your PC using the SpaceSniffer. Use the guide below to get you started. 

Download SpaceSniffer to your PC using the link above. A portable .exe will be downloaded to your system. Extract the archive and right-click on the .exe file. 

Select ‘Run as administrator’. 

Now select the drive you wish to scan. If you wish to analyze and find large files in a particular directory, then you can enter its path in the text box below. 

You will now be shown a graphical representation of your disk space usage on your screen. Simply hover over the largest chunk and you will be shown the name of the folder or file occupying that space. 

And that’s it! You can use SpaceSniffer this way to identify the largest files on your system by simply looking at the largest chunks on your screen. 

Method #09: Other third-party tools you can use to analyze disk usage on Windows 11

The world of third-party tools is a rabbit hole. The more you look, the more programs you will find that claim to help you find and reclaim your disk space on Windows 11. This huge selection of programs can be quite daunting and challenging at first, making it difficult for you to find the perfect tools that fit your current needs and requirements. If you are not a fan of one of the programs used above, then you can opt for one of the alternatives listed below. You can find a few details about each program below their listing. 

Tips to free storage space on Windows 11

If you are running low on disk space or have a smaller-sized drive that you are unable to currently upgrade, then you can use the following tips to save as much disk space on your PC as currently possible. Let’s get started. 

  • Use Disk Cleanup
  • Run SFC & DISM commands to fix errors with your drives
  • Uninstall unnecessary apps
  • Delete or Archive unnecessary or currently unused files
  • Use OneDrive or other cloud storage services to save space
  • Use an external storage device to store your libraries
  • Regularly free up your recycle bin
  • Use Storage Sense on Windows 11
  • Disable Hibernation to delete the hibernation file
  • Rebuild your search index
  • Delete additional users created on your system

And more. You can free up space on your PC using tons of ways but each usually comes with a compromise. If you are looking to avoid compromises, then upgrading your storage is the best option. SSDs are cheaper than ever and if you are looking to upgrade your storage, then an M.2 SSD could go a long way for your system. 

Note: M.2 SSDs will work at their advertised capacity only if you have a compatible M.2 slot on your system. Not all M.2 slots are the same and not all of them are routed through the PCI lanes on your motherboard. 

Free up disk space on Windows 11!

Using the numerous methods above, you can easily find what’s taking up space on your PC and fix it pretty easily. If the Windows-based solutions do not work for you, try using a free-ish software like TreeSize (or others mentioned above).
