Importing files to a PS3

Here's how you import a Theme into your Playstation 3 from a flash drive-- first, you download the files for the theme (archived together as a big file with a .p3t extension).  That file has to be in a folder called "Themes" stored as a subdirectory of a folder called "PS3", and if so, the PS3 will be able to see it and import it correctly.

If you want to import a picture or music file, on the other hand, it just has to be somewhere on the flash drive, and you have to figure out how to tell the PS3 how to open the directories and look around (not at all obvious).  Easy, once you figure it out, but a conceptually completely different process, which has been messing me up all kinds of ways for ages since I was expecting it to be consistent.  Grr.
