    I have a Mac Air (version 2) which comes with 2GB of RAM. I need to an XP shell (Parallel Desktop v4.0) to use some company based applications, which really slows the machine down. Just wondering if a Jump Drive can be used as Virtual Memory like it can be done on a Windows Vista machine? Any other suggestions on improving performance? Thanks!

    Well, I don't know the answer, but I can't believe I never thought of this question.

    If Vista can do it, then surely...

    Any drive from which an executable program gets loaded becomes virtual memory. The OS does not copy programs into ram it "maps the file into virtual memory."

    Here is more detail on the process

    So the answer is yes but it would be silly to make this happen because the disk is faster and larger
