echo Usage:
echo %~nx0 - prompt before deleting under .\CTR\engines
echo %~nx0 /y - delete without prompting
echo %~nx0 /list - list matches only, do not delete
echo %~nx0 "C:\path" - use a custom root folder
echo %~nx0 "C:\path" /y - custom root, no prompt
exit /b 0
Copy the script to /MetaDefender Drive (disk-label):/tools then run the script from there
Say "y" (yes) when asked and your disk space is reclaimed.
