I have been used Magic Folders for years now. It's not free but it's a solid app.

I would love to know exactly how these folders hiding apps do what they do... I have a feeling it's got something to do with low level access and modification of the FAT but that's just my guess. Could somebody please enlighten me. 

I pity the uninformed fools here who think Vista is no good!
Vista is an AWESOME OS....FOR MY DOG TO POOP ON!  :-\

Jokes apart - I really feel for the people who've shelled out good money to upgrade to this travesty. MS needs to seriously rethink their OS design strategy... unless it's one big Wintel conspiracy, which seems really likely. Either that or the engineers at MS are smoking something really bad.
