Great built-in Windows command line tool to use if you want to purge backup files older than… say one week.
Batch file I create to to delete .bak (backup files) older than one week:
forfiles /P “<Path to files>” /S /M *.bak /D -7 /C “cmd /c del @PATH”
From here, I set up Windows ‘Scheduled Tasks’ to run this batch file every night. Works great!
