CleanR
Wipe the contents of multiple folders at once.
...Key features include a bulk folder eraser for clearing multiple directories simultaneously and a folder locator where you can technically "bookmark" folders.
IMPORTANT NOTE:
While CleanR includes built-in safeguards to prevent the accidental deletion of critical OS directories (such as System32 or the Windows folder), it remains a powerful data removal tool. It will proceed to clear any other directory provided in the user list, which may include application data or other important files if they are targeted. Use with caution and double-check your folder list before execution.
