ROOT:\MP_ROOT\100MNV01\ - Video Files Go Here
ROOT:\PSP\MUSIC\ - MP3 Files Go Here
* Please note you can't just put MP4 (mov) files on your PSP, they won't play. You need to use conversion software encoded specificly for PSP like "PSP Video 9" or "3GP" I'm not sure what you are using but either of these should work fine. Make sure your settings are right.
Do some web searching..the info isn't hard to find.
