Two days ago, I was checking on my Local Disk to clean away unnecessary files using Disk Cleanup, i'm running a Windows Vista. then all of a sudden, my free space keeps shrinking little by little. I used a Disk Defrag option, and it worked once after 15 hours, but I had to cancel it because It was taking so long. I was able to erase something that's eating up my disk space using disk clean up after disk defrag, but it continued to shrink after a few hours. I tried the same thing again, but it's not working out. I don't know how or why that's happened and where I have to go to get rid of those unknown files that's eating up my disk space. I was at 25 gigs of free space, and now for some reason I am at 1 gig of free space and is continually shrinking. I have not downloaded any heavy files. most of them I've downloaded on my external hard drive, which only has 50 gigs of free space left.
I tried using a compress drive, but that hsn't worked either... UGH!
Any kind of help at all on how to resolve this issue would be VERY appreciative. Thank you all and God bless you.
