Harddrive free space disappearing, how to figure out what it is
I have a win7pro machine using a SSD hard drive. The last few days I have noticed my free space is shrinking. What is a simple way to figure out what is taking up the space or what is growing in size the last few days? I typically had about 30GB free space, but now only have 18 GB free and have not installed anything that I can remember.
