I have Windows XP. For some reason, the amount of free space keeps going down. I have a laptop and it has two internal hard drives, one that's around 37 gigs and the other around 45. THe one with 37 gigs is the main hard drive, the other being mainly for storage. Anyways, I don't have a lot of space left on my main hard drive, which is why I need to know why the amount of free space keeps going down. Everytime I download something, I always put it in my other drive. I haven't installed any new programs. I delete all the temporary internet files. But it keeps going down. I've lost about 200 megs already. What's the problem?
