Windows OS (How To) Free Up Drive Space Using Disk Cleanup

If your PC is running low on free space, you might not be able to install important Windows updates, and your PC’s performance may be affected. This article will give direction on how to free up drive space using the Windows Disk Cleanup Tool for both Windows 10 and Windows 11.

WINDOWS 10

Note:
To check the total disk space left on your Windows 10 device, select File Explorer  from the taskbar, and then select This PC on the left. The available space on your drive will appear under Devices and drives. 

  1. In the search box on the taskbar, type disk cleanup, then select it from the results.

  2. Select the drive you want to clean up files for, then select OK.

  3. Select the check box next to the type of files you want to delete. (To view a description of each type of file, select the name.) By default, Downloaded Program FilesTemporary Internet Files, and Thumbnails are selected. Be sure to clear those check boxes if you don't want to delete those files.

  4. To free up even more space, select Clean up system files, select a drive, select OK. When the system has done its calculations, select the type of system files you want to delete. Disk Cleanup will take a few moments to calculate the amount of space that can be freed up.

  5. After you’ve selected the types of files you want to delete, select OK, and then select Delete files in the confirmation window to start the cleanup.

WINDOWS 11

Note:
To check the total disk space left on your Windows 11 device, select File Explorer  from the taskbar, and then select This PC on the left. The available space on your drive will appear under Devices and drives. 

  1. Select Start  > Settings  > System  > Storage  > Cleanup recommendations.

  2. Review each of the categories, including Temporary filesLarge or unused filesFiles synced to the cloud, and Unused apps, and select the items you'd like to remove. Windows will suggest files for you and show the amount of space you'll save when you remove those items.

  3. After you've selected items to remove, select the Clean up button for each section.
