Can’t delete files from my USB drive

“My 32GB USB flash drive has been used to back up files. Suddenly, I can’t delete files from the USB flash drive. Both “Ctrl+ Delete” and Delete Option are not working to get rid of files on it. I have no idea of what to do to fix the issue. Any help would be greatly appreciated!

Quick solutions to solve can’t delete files from USB

Before employing a third-party file shredder for USB flash drive to force delete files, it’s wise to have a look at those easy and effective solutions. 

▶ Solution 1. Check if the files that you want to remove are opening. A file that is opening or used by another process won’t be allowed to delete. Close the files that are going to be deleted.

▶ Solution 2. Switch another USB port. You can change to another USB port to exclude that the issue is caused by an invalid USB port. 

▶ Solution 3. Run Disk Checking tool on USB drive. The corrupted file system of the USB flash drive also can be the cause of deletion failure. You can open CMD and run chkdsk e: /f to check and fix file system errors. 

▶ Solution 4. Remove write protection in Diskpart. If you have enabled write protection for the USB flash drive, you can go to Diskpart, run the following commands to disable readonly:

  • list disk

  • select disk n

  • attributes disk read only  

Note: "n" is the disk number of the USB flash drive.
