Windows 7 - mysteriously missing free HDD space
- by sYnfo
I have Windows7 installed on 50GB (Oops, it should have been 45GB, sorry) partition, and every now and then it gets full, and I have to resize that partition. I always thought it is quite normal. But it happened again today and this time, I'm sure it is not normal, because since last resizing (35GB 45GB) I did not install any new apps or whatever. Also, sum of sizes off all, including hidden & system, root folders and files is ~18GB, yet windows is indicating that all 50GB are used up...
Any idea what is going on?
EDIT:
Great tools everyone! (SourceForge appears to be offline at the moment, I'll check WinDirStat later) Alas, non of them solved my problem just yet...
Screenshot from SpaceSniffer:
On the right there is some kind of "Unknows Space", any idea what that could be?
EDIT2:
After those two apps failing to help much I didn't expect it, but WinDirStat actually helped. It showed that those missing 27GB are in my Temp folder (Well, that should have been my first guess anyway). There I found hundreds of ~100MB files, named like HTT????.tmp. After some googling it appears to be a problem with ESET NOD32 antivirus and it's ThreatSense feature.
Thank you all for help! :)
