Since I have started converting my movies to an AppleTV-friendly format using Handbrake and MetaX and even though I do all the encoding on my external drive, my hard drive space on my primary drive has been slowly disappearing from 9GB to 250MB. I searched for invisible files bigger than 500MB but didn't find anything. It is pretty weird. Anyone know what to do or where to look? Is there some freeware alternative for Whatsize to check what is eating up my space? I am kind of at a loss here so any help is appreciated.
