Freeware: Remove Empty Directories

Remove Empty Directories - New Version!
a freeware tool to batch delete empty folders

RED searches and deletes empty directories recursively below a given start folder and shows the result in a well arranged tree. Further you can create some custom rules for keeping and deleting folders. Empty files in directories can also be ignored. Just try RED to see the other features - no registry keys or system files will be touched.
