Visual Studio 2010 also may be messy
My C: partition on Windows is too small so sometimes I have problems with space. I have made a recent discovery that not only Windows itself but also Visual Studio 2010 is an out-of-space-situation helper.
C:\ProgramData\Microsoft Visual Studio\10.0\TraceDebugging
This is where you may find lots of files which will not be probably needed anymore. I’ve just deleted 2.5GB from there. I was shocked it was that much.
I recommend WinDirStat. It’s a cool and simple application that helped me to find the path given above.
