Hopefully this is an easy question to answer, but I haven't found it yet. If I check how much space is being used by my Vista account (I'm the only user) it tells me I'm using 134 GB (right-click User -> Properties), but if I actually add up all the folders under that user (there are no loose files) I only get 80 GB. Where is the other 50 GB? I've done a disk clean up and I've cleared out and reset my system restores and shadow volumes and it still doesn't add up. Any suggestions or ideas?
