x2cube released a handy tool called PSPsort. It?s a useful program to help sort files on your PSP. Here are his instructions from the readme:

?You drag the files you want into the white box and when they are all arranged correctly you click Sort! which edits the files so they display in the correct order on the PSP.You can checkmark Alphabetically Sort so you don't have to arrange the files yourself. I recommend using this with MP3s so the tracks are all in CD order, or with JPEGs.?

You can get it in our PSP download section here.
