My wifes computer (Compac Presario w/140 gig HD) showed the HD is nearly full when I tried to do a defrag. After a long search, I found that the Windows file in the C drive indicates 122 gig of "something" in it. Im too much of a noob to understand what it is or what to delete. There are 350 files of some sort named $ntUninstall......... varying in size from half a meg to hundreds of megs along with a great many others. Can someone point me in the right direction to solve this? (edit. Operating system is Windows XP

Hi Joe

Windows is a folder, not a file.

the $ntUninstall folders inside there are created when a Windows update or service pack is installed, and the data in each folder tells Windows what to remove if you ever decide to uninstall one or more of those updates.

If you delete any of those folders, you won't be able to uninstall the updates associated with those folders, but beyond that it will do no harm (except you will have some entries in Add-Remove Programs which don't actually uninstall anything because the associated folder is missing).

I personally would leave those folders alone.
I also have thousands of images, but rather than have them taking up space on my C: drive, I've bought a couple of external drives and I moved all my images to those external drives. Any new images I also put on the external drives.

Why two drives? - because one is a mirror copy (backup) of the other one. If one drive fails, I haven't lost anything.

Per your suggestion, I left those $UnInstall files alone. I did however copy them to a new folder so i could read the properties and they only added up to 2.5 gig, so something else is clogging the folder. Im going to do some more of the same tonight to see if I can determine what it is. Thanks for your help so far.

Thanks Hugh,
I ran Tree Size and the big offender seems to be a huge number of files called Windows Installer Patch. Together, they total 108 gig. Is this something I can safely delete?

What is the size of the folder C:\Windows\Installer ?

DO NOT delete anything from that folder. If you do, many programs will start popping up errors, some programs will not be uninstallable, and others will not be updateable. Be very careful!

That folder is 108 gig according to Tree Size. I should mention that my wife has been backing up to an external HD for quite some time now, and this problem seems to have started about the time she started doing the back ups. So far I havent deleted anything, per your instructions.
Thanks for the help thus far.

What file? How large is the C:\Windows\Installer folder all together?

In any case, install this Microsoft tool from either the US or Romanian sites. Don't do anything until you come back after the installation.

OK. Install the cleanup utility and come back. We can get rid of all the "orphan" files that are not needed any more.

OK, I have it installed. I started it and it has listed a number of files and programs that can be deleted. Holding at that point.

Don't delete anything there. Those are all programs that you have installed. We want to use a command line ability of that program. Close that program.

Open a command window. Exactly like this, quotes, exclamation sign, and all (paste it if possible), execute this command line:

"C:\Program Files\Windows Installer Clean Up\msizap.exe" G!

After it is done removing orphans, check the Installer folder size again.

Seems to be a problem with it. When I try to open the command line box, it flashes on and dissappears.

Did you close the program window?

Are you using Run or command line? Use cmd.exe in the Run box if you want.
