Hi, I am new to this and don't know that much about computers so here it goes. I have sony windows xp and low disk space keeps popping up. I ran a disk clean up and it frees up a little. I also have an external drive that is fairly new. I moved all I can to the I drive but how can I get everything I do on the computer go to the I drive? seems like everything still tries to go to C drive and keep getting the low disk space bubble. thanks for any help.
