Grey Folder Icons

Hey, I've been looking for the the names/author of these Icons for the last 2 hours:

Would be great if anyone knows where to find them, the author's name and if there are kinda more of them. Thanks

They are called platinum pro beta, and i don't know who makes them. I've got a copy here: http://www.sendspace.com/file/qsa1jf

(U spent 2hours, I spent 2 minutes...it ain't fair!)

They're made by VitorAngelo.

full pack: download

I've just found at deviantArt
