1. Tap on the Windows-key, type cmd.exe and select the result to load the command prompt.
2. Navigate to the folder that you want to delete (with all its files and subfolders). Use cd path, e.g. cd o:\backups\test\ to do so.
3. The command DEL /F/Q/S *.* > NUL deletes all files in that folder structure, and omits the output which improves the process further.
4. Use cd.. to navigate to the parent folder afterwards.
5. Run the command RMDIR /Q/S foldername to delete the folder and all of its subfolders.
