out of space in my hard drive
I just noticed today that my system drive c:\ has just a few GBs left while the capacity is 115GB. I remember that there is a tool which can visualize the hard drive usage. I finally found it after a few searches. Here you go.
WinDirStat: visual folder size viewer (visualize your hard drive usage)
It is very useful and I found out that
1. the paging file pagefile.sys takes 16GB
2. c:\windows\installers takes ~9GB
3. c:\Users\paullou\AppData\Local\Microsoft takes ~27GB
4. c:\debuggers\sym takes 1.5GB
...
With the above information it became very easy for me to know where to do the cleanup.
