Vice versa too, generally. Don't know if that will help.
A shop MIGHT be able to transfer the files over for her if she brings them both machines (is the Mac also a laptop?).
I'd ask on a the Mac or Mac Hardware Forum.
Is this a PC question? Or a Mac question? Or a hardware question?
My sister-in-law must bought her 2nd computer, a new Mac. She has been using an old Toshiba laptop for 10+ years (not sure, probably Win 95), and she has limited technical skills. She is in Atlanta so I cannot inspect the machines. Personally I know nothing about Macs. My best guess is that the old laptop has no USB, no CD burner and no network adapter but that it does have a floppy drive as well as serial and parallel ports. The new Mac presumably can read DVDs but not floppies. I don't know whether they have serial/parallel ports.
Any thoughts on how to transfer files from the Toshiba to the Mac? I've asked her for more information but I am not confident she will be able to answer my questions. She's smart, but not at all technically oriented.
My impression is that newer Macs should be able to read CDs generated on newer Windows system but I'm not even sure of that.
Any suggestions for how to proceed?
My off-the-cuff guess is that the easiest solution is to have a computer shop produce a CD of the files.
