With hard drives getting cheaper and cheaper, it gets less likely that you run out of space than it was a few years ago. Still, you may not want to upgrade that particular drive for one reason or another. Or you are really collecting a lot of stuff.
If you don’t quite know what is taking up the space, then you can call WinDirStat to the rescue. It is a free program which you can download at http://windirstat.sourceforge.net/.
It scans your hard drive – or just some folders if you wish – and then displays how much space the items are taking up.
While it does have a funky-looking graphical display, personally, I find the text display more useful. (My wife really likes the graphic display though.)
And with file-deleting capabilities just a right-click away, it re-calculates file usage immediately when you remove files from within the program.
Maybe you’ll find some long-lost humongous files you forgot about and can delete? I was able to clean up about 20GB of files I had all forgetten about and don’t need any more.
