Case of the dissapearing Gigabytes

[Saikii]

A few weeks ago I approached my professor about the small amount of megabyte free space I had. After removing a program or two, about 7 Gigabytes were freed for use. However after working on a few projects, I discovered that the size was back down to just a few Megs. I went through and deleted all the old projects that I didn`t need, but somehow that space keeps filling up. I look at the add remove feature on my laptop and can tell that is not where all my Gigabytes are or where all the space is being taken. Does anyone have an idea of what could be taking up all this space? I`ve tried clearing caches, removing programs, and disk defrags. None of that seems to work.

Have you tried a virus scan?

try a virus scan then use a registry cleaner that should at le4ast free up some space.

Well, what are you working with? If you are doing a lot of video editing, that eats up space very, very fast.
