C drive-erratic free space.

WinDirStat shows hiberfil.sys as taking up 99.9%
of C drive. i just found THIS, it may be the answer.

TreeSizeFree shows that Windows is taking up
390 gigs of hard drive space. WinDirStat shows
it taking up 23 gigs. ( Mods, if next comment
is unacceptable please feel free to edit it )

WTF ??

Backup size is appx 24GB

TreeSizeFree shows 379 windows files of appx
1 GB each. Path is C:\Windows\System32. Names
are .data, 2.data-379.data

WinDirStat shows 387.2 GB of C drive as
"unknown"

"ARRRGGGHHHH !!!!!!"

i just deleted 380 1 GB .data files from
C:\Windows\System 32. Free space is
now 388 GB of 419 GB.

Update: tried running an error check ( not that i
thought it would work, but worth trying ) no help,
still the problem. Backing up "C" to an external
hard drive now. Interested in seeing how much
space the backup takes up. i may format C and
restore from external. Certainly not my preferred
solution.

Saving a ghost image would probably be more telling. But then you need to see if the left over free space varies there too, which is very douptful.
Let us know what you find out.

My 120 gig C drive partition yesterday reported 62.4 GB free. Today I get a warning telling me free space is dangerously low.
Checking it I see 53 mb free and checking it again 5 minutes later I see 26.7 mb free. System restore is configured for 11% (13.21 GB). The other partition on this 250 gig drive is consistently reporting 69.4 GB free.
When I do a restart I get totally different numbers for that C partition such a 43 GB free and something else again an hour later.
Kaspersky has done a full scan and found nothing.
Any help will be very much appreciated.

You should also check to see if the hybernation file in the root directory may be an issue slowing your computer down.
I have turned mine totally off which speeded up my computer especially when I shut it down. I still can put it to sleep without an issue.
Here is the DOS command to turn it off.
Access CMD prompt using Run as Admin
powercfg -h off
Just cut and paste what I wrote above with the spaces.

already done, see my first post on this page. As per
previous post i now have 387 GB free space on "C"

Computer running fine and 385 GB free space on "C"
