I was frustrated with the manual busy work of cleaning appdata leftovers and how much most traditional cleaner apps miss. Most cleaners I've used in the past simply check a fixed list of common junk folders.

I've been playing around with an app idea I've called ChillSweep, a free, open-source cleanup tool for Windows and Mac. ChillSweep checks folders against what's actually installed on your machine, and can claim back huge amounts of disk space other cleaners can't see.
