Well, the reason I asked was because free space had been pretty stable, across multiple sessions. Then there's this sudden increase in free space. Makes me wonder what got nuked to account for it. Seems like an awfully huge amount for swap file or system restore to account for.
I've been running defraggler over several sessions when not using my PC. I have a 1 TB drive. Tonight, I noticed free space increased dramatically, by 20 GB or more. Is this normal, or did Defraggler damage/destroy some files on me?
