I have a 16 year old friend whose pretty opinionated. She insists that the pagefile should be on her C drive because it is the the system drive and some "TECHNICIAN" told her so :S. Drive C (just 4GB) contains her Windows XP and it's running out of space so I told her to move the pagefile to her second drive. She did so but apparently during heavy usage of Paint Shop Pro got a warning about low virtual memory. So she has put the pagefile back on drive C and won't move it now. I'm going insane trying to convince her so please help me out here. What do you guys think? Is there any truth to the optimum performance claims of placing the pagefile on the same drive as Windows XP? Please post lots of replies so she can see that I'm not the only one who thinks this is absurd. Also, I told her she won't get out of virtual memory warnings if she upgrades to 3GB ram and turns off her pagefile. Correct? She's just a home user.
