I have a work computer (Windows XP) that is partitioned into a C and a D drive. The C drive is allocated 20GB of space, and is currently hovering around 500MB free.
I scanned it with TreeSize Free to show me where the problem areas are, and there are two:
1) C:\WINDOWS\options
There is a good 5GB of space being taken up here by old setup files, however I am unsure if I can safely delete them. Are they used for uninstallation, or are they simply artifacts of old installs and can be removed?
2) Multiple user directories
This computer was shared by the whole department before it came to me. Now I am the only user, and would like to clear out this area as well. Can I simply delete their user directories?
edit
I have already run Disc Cleanup, and that freed about 2GB of space for me. What I'd like to do is get some extra breathing room on top of what has been already freed.
