HP prime memory

[xgarlanx]

Hi, i'm new to the forums. I was trying to put some PDFs on my prime but i can only seem to put 2 max. when i try to put the 3rd one the HP freezes and the connectivity kit also does. each pdf is about 800 KB. is it because there is not enough space? i've tried with diferent files but they are about the same size. they are the only things i've ever put on my prime.

i used Mviewer GX to convert the PDFs into programs.

sorry for my bad english.
