7.5 GB of disk space has gone missing from my C: drive.
It's really frustrating - my C: drive is only 20 GB to start with and I now have only 500 MB free, so I really need to figure out what's going on.

Windows Explorer shows C: drive properties of 20 GB disk size and 500 MB free.
I have made hidden files visible. If I add up all the folders under the C: drive they come to 12 GB (almost all in C:\windows).
I have my virtual memory set to all go to the D: drive. My recycling bin is empty. I have set System Restore to use zero disk space. I ran chkdsk and all looked OK.

I ran "disktective" and it shows that I have a single file in the C:\ directory that is 7.5 GB in size, but doesn't tell me what that file is or how I can get rid of it.
I tried "attrib -s | findstr SHR" but didn't turn up anything significant.

What the heck is going on? Anybody know any good disk utilities that might help?

do you have hibernation turned on?

Also note, any 20g drive is sure to be out of warranty and near end of life.

500g drives are 50.00

backup yer stuff.

Sure it is not a system volume information file (system restore) or a backup file?

hi,

Windows 7 creates a separate partition on a hard drive for important windows files for example boot files and etc. and it cannot be deleted.

Also, it may be a manufacturers hidden recovery partition to restore your system to factory settings.

IMHO I would do as Ken-in-West-Seat... has posted. Just stick a bigger hard drive in and be a happy computer person again.

It may be old System Recovery files. To clear old System Restore sets - Log in as Administrator, Open COMPUTER, Right click on C: Drive, Select PROPERTIES, Hit DISK CLEANUP and let it do its work. When the results come back Select the MORE OPTIONS tab at the top and then hit CLEAN UP under the System Restore and Shadow Copies heading. Then keep selecting Delete and OK until it has cleaned everything up. You should then Defragment your C: Drive.
