If you’re on Windows and you’re trying to delete a folder but you get an error like the following:
Folder In Use
The action can't be completed because the folder is open in another program
Close the folder and try again.You can easily close / kill all processes / handles / DLLs that are using the folder by using a program called Unlocker. If Unlocker can’t find an processes in use, you can still have it delete the folder immediately or after a restart.
