    I've got two scans of the same volume, in this case before and after some
    automated file cleanup, that I would like to diff. I have both saved as
    .gpscan files. What's the best way to accomplish this? I get that I might not
    be able to do it graphically, but with that caveat in mind I can't even figure
    out how to do it
    at all*. I'm willing to accept, "export to a list of
    files+sizes in plaintext and diff" but I can't even figure out how to export.
    Ideas are very welcome.

    I am afraid there's no easy way. The best I can think of involves writing a
    custom script that converts a .gpscan file to plain text output, where the
    output has a line for each file containing its full path. This output can then
    be easily compared using sort and uniq. Writing such a script is also not too
    difficult as long as you use a scripting environment that supports parsing
    XML. Nevertheless, it does require a bit of programming.
