MYSTERIOUS FILE(>1G) IN C:\WINDOWS

[cooler]

I just found out that the size of this file (named 652.) is exactl
1giga bytes (1,048,576 kB). This seems like that there is one routin
having set the upper limit of its file size which is 1G.

It is shown in win explorer that it is a hidden system file. If I tr
deleting the file, it says 'Cannot delete 652: It is being used b
another person or program. Close any program that might be usingth
file and try again.'

by using process explorer and finding the handle, found out that th
'System' process is using the file c:\windows\652. I could close th
handle to this file.

Sometimes XP can keep working without any problem. But this 1g fil
disappeared and the space it occupied were released. When I next tim
reboot the computer, this file appears again.

Sometimes the computer would immediately reboot as soon as I close th
handle to this file by using process explorer. After rebooting, thi
file is still sitting in c:\windows and still having the size of 1G!

Help

How much memory do you have on your computer? I am going to take a
guess at 1 GB. You may be looking at your hibernation file though I
haven't seen it show up like that. It is also possible that it is your
pagefile, though I haven't seen it show up like that either. These are
both usually found in your C:\ directory. If you have done spyware and
antivirus checks and the computer is running fine, I wouldn't worry
about it.
