use exactly as much memory as it needs, at the point it is. If it uses 100% [or near to] it will resort to using virtual memory [also called swap file or page file].
If you told us what Operating System as is requested in the red text, we might tell you more.
For example, Win 9X and ME can have trouble with too much memory.
Running from the CD should basically be slower and offer nothing unless if you don't have enough Hard drive space [which some call memory, but is an entirely different animal].
First of all, thank-you to whoever got my login straightened out, after I screwed it up.
I know basically nothing about RAM, except that I use a bunch of it doing art work and serious photo editing. I'm going to increase my RAM within a few months; in the meantime, would I be better off to remove my photo editing program (MS Picture It! Photo 2002) from my hard drive, and use it on disk? Would this save memory, or, does it take roughly as much memory to run the program from CD?
As said before, I know nothing about this. Thanks for your help in advance -- and thanks again for all your past help.
