How to Delete Backup Files in Windows 10

Creating file backups is important to safeguarding data. Some users back up files with backup tools to keep secondary copies. Windows 10 also automatically backs up data files without users realizing it. However, an excessive accumulation of superfluous backup files can waste many gigabytes of drive storage space. Therefore, some users might wonder if they can delete backup files in Windows 10 to preserve storage drive space.

Two types of backup data can waste drive storage space for Windows 10 PCs. User file backup data is for files like word-processed documents, spreadsheets, images, videos, music, and presentations. Those are file types users typically keep backup versions of with Windows 10’s built-in File History utility or third-party tools. File History automatically backs up user files to selected storage drives. Enabling that backup utility can lead to an accumulation of old user file versions dating back years, which wastes disk space.

Windows 10 keeps system file backups for system restoration, the other type of backup data. Its System Restore utility saves restore point backup data that users can select to revert their PCs to earlier dates. Windows 10 also temporarily saves a backup of the previous OS version installation after installing a new build update. System backup data can take up lots of hard drive storage space.

A combined accumulation of superfluous user and system backup files will leave your PC’s drives with less storage space for new software. So, it’s a good idea to delete less essential backup files that are wasting space. There are a few ways to delete both user and system backup files kept by Windows 10’s tools. If you’re wondering how to delete Windows 10 backup files, check out the alternative methods below for erasing user and system backup data.

Method 1: Erase old Backup Files via the Control Panel

If you utilize File History in Windows 10, your PC’s storage drive might include backup file versions dating back years. Fortunately, there are three ways you can erase backup data kept with File History. This is how to delete backup files in Windows 10 within the Control Panel.

Step 1: First, click the search box or magnifying glass icon by the “Start” button on Windows 10’s taskbar.

Step 2: Enter Control Panel within the search tool’s text box.

Step 3: Click “Large Icons” on the “View by” drop-down menu.

Step 8: Press the “Clean up” button.

Method 2: Delete old Backup File Versions via the Command Prompt

Step 1: Alternatively, delete old user file backup versions preserved by File History with the Command Prompt utility. To do so, bring up the search tool in Windows 10.

Step 2: Input the keyword cmd within the search box to find the Command Prompt.

Step 3: Next, right-click Command Prompt within the search results to select a “Run as administrator” option for it.

Step 4: Now input the command fhmanagew.exe -cleanup 0 and press Enter to delete all but the latest file backup versions.

The fhmanagew.exe command

If you don’t want to delete all but the latest file backups, you’ll need to modify the above command by changing its cleanup value. These are some of the alternative cleanup values you could enter for the fhmanagew.exe command:

  • fhmanagew.exe -cleanup 30 – Delete file backups older than a month
  • fhmanagew.exe -cleanup 90 – Delete file backups older than three months
  • fhmanagew.exe -cleanup 180 – Delete file backups older than six months
  • fhmanagew.exe -cleanup 270 – Delete file backups older than nine months
  • fhmanagew.exe -cleanup 360 – Delete file backups older than a year
  • fhmanagew.exe -cleanup 720 – Delete file backups older than two years

Method 3: Configure File History to Automatically Delete Old Backup Files

Instead of manually deleting Windows 10 backup files with the methods above, you can configure File History to automatically erase old backup data. By default, File History is configured to permanently keep its backups. This is how you can configure File History to erase backup files after specified periods.

Step 1: Click “Start” and the “Settings” button on the menu.

Step 2: Next, select “Update & Security” to open the Settings window, as shown directly below.

Method 4: Delete System Restore Point Backup Files

A restore point is a backup of Windows files for a specific date. Although System Restore is a handy troubleshooting tool, most users probably don’t utilize it that much. If you don’t need saved restore point backups, you can erase all current ones and minimize that utility’s disk space usage.

Step 1: Press the Windows key + X simultaneously to bring up a Win + X menu.

Step 2: Click Run on the menu to open that accessory.

Step 3: Next, input SystemPropertiesProtection in the Run’s Open box.

Step 4: Press the “OK” button to bring up the tab in the snapshot directly below.

Step 6: Now press the “Delete” button to erase all current system restore points.

Step 7: Drag the “Max usage” bar left to reduce the maximum storage space allocated to restore point backups. Windows 10 will then automatically delete older restore points with greater regularity.

Step 8: Click “Apply” to save the new settings.

Step 9: Then click the “OK” button to exit System Protection.

Method 5: How to Delete Windows 10 Backup Files With Disk Cleanup

Windows.old is a backup folder for your PC’s previous Windows 10 build installation that’s kept for a month after you’ve upgraded the platform to a new version.

This is how to delete Windows 10’s backup folder with that tool.

Step 1: Click “Start” on the taskbar to open the menu.

1. Are the above methods for deleting backup files only applicable to Windows 10?

The fifth method for deleting the Windows.old folder applies to Windows 10 only. Methods one, two, and three are relevant to Windows 10, 8.1, and 8, which are the platforms that include the File History utility. Methods four and six apply to Windows platforms dating back to XP.

2. Can I erase backup files in Windows 10 with PowerShell?

Yes, you can erase backup files by entering the same fhmanagew.exe commands for method two in PowerShell.

3. Are temporary files backup files?

Not exactly, but some temporary files are saved by applications for backup purposes. Some office suite software packages have autosave features that save temporary copies of user files. That backup data enables users to restore unsaved documents after applications crash and unexpectedly close. You can delete temporary file data with CCleaner, Disk Cleanup, and other system maintenance software.

4. Can I manually delete File History backups within File Explorer?

Yes, you can access a File History folder on your chosen storage device so long as the “Hidden Items” option is enabled on File Explorer’s View tab. Then you can open the Data subfolder within that folder to erase backup files with Explorer’s “Delete” button.


Don’t let unneeded backup files hog too much space on your Windows 10 PC’s internal or external storage drives. By deleting user and system backup data with the methods outlined above, you can reclaim gigabytes of drive storage space. If you don’t want to erase many user backup files, make sure you at least erase Windows 10’s backup data with the Disk Cleanup or CCleaner utilities.
