C: drive full, but folder sizes don't add up

I don’t know where all the unaccounted disk space usage is coming from on the C: drive of our Windows 2008 Server. Total folder sizes from below is only 21.4 GB out of a 39.9 GB partition – but disk is showing full (only 187 MB available) and low disk space warnings are being given in system tray.


C:\Folder - Size

Dell - 64 KB
Diskeeper - 77.7 MB
inetpub - 1 MB
Install - 75 MB
PerfLogs - 0
Program Files - 247 MB
Program Files  (x86) - 345 MB
Tech Support - 2.64 MB
Users - 378 MB
Windows - 20.3 GB

Get a copy of TreeSize (Jam Software) and install the trial version (it is worth bying). It will show you all the file/folder useage on your server including hidden and shadow storage.

Thanks, but I only have 187 MB of space available. The Symantec antivirus won't even update and I think it is related to that as I have seen other reports of similar problems with Symantec Endpoint Protection, but I just can't find where I can make enough space.

Problems using Powershell and Active Directory?

Managing Active Directory does not always have to be complicated.  If you are spending more time trying instead of doing, then it's time to look at something else. For nearly 20 years, AD admins around the world have used one tool for day-to-day AD management: Hyena. Discover why

I think Tree Size will install in that space. Have you tried?  

Also run DiskCleanup (cleanmgr) to clean up temporary files first. .... Thinkpads_User

TreeSize Professional can be installed on a USB key. So do that and run from the USB key. That will tell you in a hurry. I use TreeSize myself, so I recommend it from that viewpoint.

I just got Disk Cleanup (cleanmgr.exe) setup, was wondering why that wasn't available. http://technet.microsoft.com/en-us/library/ff630161(WS.10).aspx

Thanks for the info on that first, I have it running now, but will have to finish later. I will then check out Treesize and let you know how it works out.

Did you empty the trash?
Also, you can right click on the drive and optimize.  There may also be a lot of cached and temp files that can be removed.

Check what your page size is set to.
Properties of computer, advanced settings, performance settings, advanced,

You might not have the paging size set to a fixed side but rather allow windows to manage it which may have it grown larger than expected. Reduce the size to 6GB and that should free 12gb after restart.

Thanks all, I had tried the other solutions, but the trial of TreeSize Pro did it for me. I first got cleanmgr.exe setup and was able to free 1GB for some working room. Then TreeSize found 20GB being used by my Diskeeper Recovery Bin where I deleted 15 GB worth of old Symantec update files. I wasn't able to access my Recovery Bin, where I could have possibly deleted those files, probably due to the extremely low disk space available - but TreeSize quickly found them. Thanks Thinkpads_user, it is a great program and thanks for the video link n2fc. Good point ve3ofa, I will have to check that out; I was trying to see if any folders were hidden and they must be, but I will have to look that up for Server 2008 R2.
