first answer - yes i use flash fxp, it worked on 3d dot game heroes fine. but when i try to copy star ocean from my laptop to my ps3 he transfer the first files, and when it comes to the 22gb bin.file he transfers arround 14gb and then he says something like "there is to much time gone blablabla". i'm not at home so i can't tell you the exact error.
but the main problem is that the external hdd i use now is not mine. so i cant use it forever. so i wanted to use the flash fxp way.
i will write tomorrow what flash fxp says, also i will test tomorrow 4gsplit or the other tool instead of Open Split.
