DotsSweep is a small desktop application that lets you delete invisible files (ones whose file names start with ._) in a folder of your selection recursively. Actually, you can clean up multiple folders all at a time.

If there are invisible files in a folder, what's the big deal? The question depends on how you use that folder. For example, if you use Xcode to develop iOS or Mac applications, that can cause a serious problem because referencing files directly to an existing folder can prevent you from sending a binary to iTunes Connect with Organizer. Also, if you have a folder that contains image files, importing it to other operating systems like Windows can make invisible files visible and make a mess.
