Last night, I tweaked my computer a lot because I was trying to solve DLL problems. While that didn't work, I must have done something that fixed a glitch somewhere, because my free space jumped from 8 GB to more than 9GB. This morning, it was still the same. However, when I checked up on it just now, it's back to 8 GB. I haven't downloaded any large files and in fact I've just deleted some things. Any ideas on what might be wrong and how I can fix it? Thanks!
