I just did yesterday exactly the very exercise you are asking about,ie transfered the folders containg my music/photos/filmclips ect plus a few text files stuff like that no probs,just stuck the windows XP 32 bit disk in as slave to the new master Win7 64 bit,opened the old disk,opened the desktop folder and just dragged the folder I wanted to the desktop on the new master disk and bobs yer thingy.
PS There is probably a much easier way of doing this but this method has served me well for the last quarter of a century.
