This tutorial shows you how to permanently or temporarily delete files & folders in Windows using Context Menu, Keyboard shortcuts, CMD, PowerShell, etc.

Another easy way to automatically delete old files on your Windows 11 PC is to use the Command Prompt. You just need to run a few commands and the auto-delete function will work.

From the command line, type "backup.bat" and the batch file will run your specified commands: first, copying all files from that directory, then renaming them to remove the extensions.
