Hello all,

I have WinXP installed and Windows Explorer is reporting that I'm using
16.3GB of space on my 80GB hard drive. I have about 7 folders on root drive
C: and I manually calculated the space myself and I came up with about 6.6GB
of used real estate. Strange huh!

I thought maybe there's some hidden folders so I went into Explorer Tools,
Options, View and selected (Show hidden files and folders) and then unchecked
(Hide protected operating system files). Same result.

I can't see where the other 9.7GB of space is being used. My drive is not
split into separate partitions so that can't be the problem. I'm perplexed
about that almost 10GB of missing hard drive space. Has anyone else
experienced this?

By default, system restore is set pretty high...way higher than needed...
that might account for at least some of the space you cannot account for

Have you checked for Temporary Internet files and also the Recycle Bin?
Also System Restore Points and Windows Update folders
($NtUninstallKB.....$).

Have a look a Disk Cleanup to see what it reports.

Philo,

Is there anyway to control the amount of disk space that System Restore uses?

It could be the reserve for the Master File Table

http://support.microsoft.com/kb/174619

Because of the importance of the MFT to NTFS and the possible impact on
performance if this file becomes highly fragmented, NTFS makes a special
effort to keep this file contiguous. NTFS reserves 12.5 percent of the
volume for exclusive use of the MFT until and unless the remainder of
the volume is completely used up.


That's no small amount.

JS,

Your mention of Windows Update folders lead me to the Windows folder where I
discoverd something quite interesting. Under the Windows folder are several
other folders blue in color that all begin with ($NtUninstall). I think
these folders are used by Windows to undo whatever was changed on your system
during the Windows Update. It appears that the Windows Explorer does not
include these folders when calculating disk space. Thus, my missing 10GB of
hard drive resides within those folders.

So now I have a new question to ask. Since I won't be reversing anything
changed by Windows Update, is it safe to delete all those ($NtUninstall)
folders?

WaIIy,

Wow, now that's interesting. I never knew about this but since my volume is
FAT32 that would not apply in this case would it. Nevertheless, it's still
good to know these things and I certainly appreciate the FYI :-)

These folders and associated files in these folders are safe to remove,
however once deleted you will no longer be able to un-install a patch or
update that was associated with the deleted folder/files.
I would keep the most recent set (last two months just in case) of folders
and delete the older updates.
As a safety net I burned these folders to a CD before deleting them.

Warning: One folder you should not delete is: $hf_mig$

To All Responders,

I found out that's it's ok to delete those $UnInstall folders under the
Windows folder. I wish to thank all who responded to this thread. I
appreciate your comments and suggestions to the max ;-)

Note: 10GB of $NtUpdate... folders, I don't think so, you should check to
see what Explorer reports if you choose to delete them per my previous post.
