Hi, I just bought my first Sony Mp3 player (not counting my old K750i sony ericsson). Of course the first thing I noticed was: I can't easily transfer files to and from the mp3 as it is with my K750i. I read about GYM, about the mp3 jar transfer utility, etc... but I wanted to ask for something more definitive: is there a away to transfer files to and from my NW-E505 without having to install any application? I tried the jar utility (with ffmpeg) and the music transfer can be played through the jar player but not the flash player: it gives me a "MG Error" hope anyone can help this newb
