Remove Empty Directories will surprise you in the same way you're usually surprised when running a temporary file cleaner. You'll be simply amazed to see how much space you can waste also on empty folders.
This little tools analyzes your hard drive (or just the folder you select) in search of empty directories, so that you can delete them afterwards and have a cleaner, better organized hard drive.
The program's settings allow you to set some basic rules and filters to modify its behavior. However, there's no backup, restoration point or anything similar so if you delete something important, it's up to you.
The whole process of scanning and deleting folders takes only a few minutes. What's more, you can run it from the folder's context menu, as Remove Empty Directories is integrated with Windows Explorer.
