I used the whatis program and found out it is using 26 gigs of hard drive space. I have a lot of programs installed but should I be worried?? I have mainmenu as my system cleaner but no option to clean up unused files in my libraries folder would onyx be a better choice?? I have appzapper installed which grabs the files when I uninstall the application. Should I just ignore it then? Any help would be appreciated.
