C: drive filling up - SBS 2011 Essentials ?

We installed SBS 2011 Essentials a few months ago, with a C: drive of 60GB. At installation, it was about 20GB used, 40GB free.  We've just started reveiving disk space warnings, and the drive is now 56GB full, only 4GB free !   I've tried to do searches for large files, log files, etc. but nothing is sticking out as a main cause for this drive filling up.

First question: is there a likely place I should look to find out what is filling up the C: drive ?

Second, is there some utility I can run to summarize the sizes of all the folders to see if there is a "smoking gun" ?

I would recommend looking at the \Windows\winsxs folder as the folder consistently grows until it reaches a large size.  Unfortunately there is no safe way to "prune" the folder.  As well, make sure you disable hibernation as it requires a file in the root of your hard drive atleast as large as your RAM size.  To achieve this open a command prompt and run "powercfg -h off"

Turned off shadow copies and it only freed up about 2GB.  Tried the "powercfg -h off", but even though I'm logged in as administrator, it returns "You do not have permission to enable or disable the Hibernate feature". The Windows\winsxs folder is about 8.9GB -- but you say there is no way to clean this out ?

You have to right click command prompt from start menu and choose run as administrator. And there is no safe way to clean the winsxs folder

Have you free'd up that space? Everything ok?

Got rid of the sql temp file ... much better for now.  I'll need to spend more time on it later.

Glad I could help.

I don't use TreeSize - I prefer WinDirStat - however, BOTH programs suffer from a permissions issue, especially when run on 2008 and later.  One way to PARTIALLY get around this is to run WinDirStat on the UNC path for the drive and not the drive itself using the administrative shares.  Install it, run it against \\servername\c$ instead of C: - this can show a more complete usage of the drive.  It also shows you "colored boxes" that can help you identify files quickly AND can help you identify types of files so you can see if logs might be your problem.
