FolderCleaner deletes .DS_Stores files, resource forks and .Trashes folders from a folder or an external hard drive.
What's New
Version 1.1: added possibilty to eject the volume that you choose with administrator privileges (if you choose something other than a volume, it will be ignored)
Hmmmm, no drag & drop support? It would be nice if it could be added to the Finder windows' toolbar for automatically action on the selected disk/folder. It has some English errors too: I guess you meant 'external peripheral'.
