And if you don't already know… Mediumgauge's PSP Filer simply gets the job done. Manage both directories and files on your memory stick, UMD, and flash0/flash1. Also take advantage of the integrated tool-set enabling you to rip UMDs directly to your memory stick, view pictures, text & binary files, listen to WAV/MP3 files, and the fun doesn't stop there. PSP Filer is available in many languages - see the appropriate "readme..txt" for further details.
