I have a Windows 2008 SBS. It has been online for a few months now. When the original setup was done the OS and all Applications took 30GB of space for example. My partition was 70GB so I had 40GB leftover. Since then I have not installed anything. Exchange, WSUS and Sharepoint have been moved to a different partition. I should still be at 40GB but I am now down to 10GB of free space. Nothing should be writing to C drive but something is chewing up all that space. I have no virises either. Has anyone come across this? Danny

You can search the disk for files with today's or recent date modified to find the, most likely, log files location. Regards, Dave Patrick .... Microsoft Certified Professional -Microsoft MVP [Windows]

do you think it is log files?

More than likely yes. Regards, Dave Patrick .... Microsoft Certified Professional -Microsoft MVP [Windows]

Can't find it. Do you have a specific directory. Windows folder=19GB Program Files=4GB Program Files x86=4G rest of folders =1GB My partition is 65Gb - 28Gb= 37GB should be free. I am at 10GB. 27Gb of log files?? I disabled shadow copy and erased previous versions and I got nothing.

Found this post which explains what is happening. Winsxs folder in Windows Directory and log files for WSUS services in Inetpub. http://simultaneouspancakes.com/Lessons/2010/01/13/recovering-hidden-disk-space-used-on-sbs-2008-c-partitions/
