Introduction: Remove Undeletable Folders or Files With WinRAR
Some files or folders can't be deleted or renamed, mostly made by a bad coded VBS script or torrent.
Like "Bad folder " <- it has a space in name at the end and it can't be renamed or deleted.
Step 1: How Is Made
Right click on the folder
Select “Add to archive” option (Make sure that you have WinRAR installed on your machine).
Tick "Delete files after archiving" check box displayed under "Archiving options" section.
Leave all other settings as they are and click "OK" button.
The .rar archive will be created on your machine, and your painful folder will be deleted automatically.
Now you may delete this *.rar file whenever needed.
