Question

my brother has a psp and i think he might have deleted the MP_ROOT folder. he wants videos and we got the PSP video converter. i looked up what might be wrong but everything says just to add a new MP_ROOT folder and then some others. it doesntt work!!!!!!!!!!!!! is there any way he can get a video?!?!? hellppp meee!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

Answer 1

The video goes in the Video folder. (drive):PSP/VIDEO

The ROOT folder is the memory card its self.

Answer 2

just format the memory stick on the psp . go to system settings and format memory stick and then when you load it back up on the PC it should be right back there. but make sure you back up your saved games and pictures music and all that because once you format everything on your memory stick will get deleted
