There are specific situations where this might be advisable, such as
when configuring multiple paging files on a system with more than one
physical hard drive.
But in general the system managed size is a good choice.
For detailed information about the paging file and related memory
management see the article by the late Alex Nichol MVP at http://aumha.org/win5/a/xpvm.htm
Good luck
