the concept and the design for the Recycle Bin is lifted straight from the classic Mac OS's Trash.
Mac OS's Trash has a hidden folder on the hard drive called... "Trash". It's not just hidden, it's one of a few folders that is fully inaccessable using the Finder.
MS tried to do this, but you can't fully hide any file in Windows, because too many dorks care about hidden folders and files. Shit that they shouldn't ever mess with.
But yeah, where did you think it was at?
