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" ?
