How to find disk usage of folders in Windows
Best program to visualize file system usage on Windows?
What’s using up my disk space?
Windows 7 - mysteriously missing free HDD space
C: is getting really really low. :P
I used to use a program from moleskinsoft.com to do this task (it has since expired), but I need a nice free application that looks at one of my drives and tells me how big each folder is and where all my space has gone.
