Okay, while I was playing around with my iTouch and tried to backup the whole /private/var/, I found that musics and videos synced from iTunes are saved in /private/var/mobile/Media/iTunes_Control/Music/F**. I wanted to put music and video files into my original player without the need to pass iTunes, I wanted to know how to put them right. Since they are organized in a way that seems having no pattern(like F00-F27 are empty and then there is one video in F28 with the name WLAP.mp4), I wondered if one of you will figure out how this is organized. I don't know how the names of the files are sorted, but they are like (4 capital words).* so don't ask me how they are named. I'm sorry if my english is unpolite or my grammar is wrong; I am a South Korean.
