I have an HP notebook running Vista Pro and it has a 72gb hard drive. I am down to about 2.5 gb of available space. I have already deleted a number of seldom used programs. The entire Program Files folder contains about 32 gb. My Documents are about .5 gb. I have deleted temporary files and can't figure out what is occupying the other space (no doubt Vista itself is taking a good bit). Short of installing XP and starting from scratch, I'm looking for suggestions on how to free up some space. Also, when browsing the Net, I often get a dialog box asking me to open or save a .php file on Glocktalk and other sites. The page will not load. I need to reboot and everything then opens fine. Related to disk space issue?
