How do I solve Disk Space issue on Windows Server 2008 SP2

Issue:
 We have received a warning message about disk usage on one of our servers (TAPI Server 1). The Disk space on that server by right clicking on C drive >> Property as follow:
Disk space = 29.9
Free space = 2.33
Usage      = 27.6

The size for all the folders/files in C drive (after un-checking "Hide protected Operating System Files" option, then going into C drive and select all of them) is 19.1. So we is this 8.5 GB extra from??

The Server is Win 2008 SP2 (have IIS and used as TAPI server).
 (Note: we have a number of servers doing the same function for diff regions)

I have checked the following folders on number of servers (TAPI server 1, 2 and 3):
"C:\Windows\System32\LogFiles" (has 40 MB), and  
"C:\inetpub\logs\LogFiles" (has 775 MB)

I have carried out a search on the internet and I am unable to find a solution to locate and reduce the disk space.

Thank you in advance.

It can be that it is the swap file that is 8.5Gb as reserved space. I don't now if you use a swap file but this can be it. Or all the temporarily files from all the updates consumes that amount of space.

You can try to clear the drive from all these files and see if it makes a difference.

as bright12 telling, it may be your pagefile.

check C:\pagefile.sys file (what is the size of this file). This is hidden file so you need to enable hidden protected system files - which you did already

If you have additonal partition like D, E ...etc, then you can move the pagefile to there. Follow instruction below. (almost same), but

But for C drive, set it to "No Paging File", then click Set .

Point to the other dirve and make it "System Managed" then click Set


reboot the machine

2008 doesn't allow you to delete the un-install files associated with updates until you install a service pack. It should clear the updates un-install files when the service pack is installed but, you can also run the 2008 SP2 cleanup tool (after installing SP2) - Compcln.exe - http://technet.microsoft.com/en-us/library/dd351467(WS.10).aspx

Thank you everyone for that. I have found that "Problem Reports And Solution" is giving me all that as it stors all the errors.

I have solved my issue by doing the following:
1. I have backed up the files.
2. delete the files
3. turn "Problem Reports And Solution" off.
