Why did my computer say I only had 100GB left??

I opened up my computer a few times and when I opened it up 4 times it didn't say anything under C;/ and then I clicked it again and it said I had 100GB left but now it says the correct amount, was it just a glitch?

How big is your hard drive?

500GB.

Do you have any other partitions?i-like-pie

Yeah I have about 2 or 3.

This is a pretty vague question. :P

How much data do you know you have on your drive? What was the correct amount of free space you expected to see? How big are each of these other partitions?

Treesize Pro is a program you can download that will break down the contents of your drive visually so you can get a good idea of what's taking up what. Free space will fluctuate normally (swap files expand and contract when they are managed by Windows, temp files get created and deleted, etc). How far off was 100GB from the amount you expected to see?
