i've tried this, but it still transfers over as an mp3

I have searched this forum for the problem of converting MP3's to Atrac and have tired using the VAIO music transfer program, but it still doesn't solve my problem. From what i can see the only way to convert MP3 to atrac on ss is to select the album, select all tracks, right click, go to convert format, then i click to do it to atrac3plus at 64 kbp. This converts the file, but then you are left with an mp3 file and an atrac file. The only way i can see to make sure the file that gets transfered to my player is atrac and not mp3 which takes up more space and drains battery) is to do the extremely long, slow process of clicking on each song, going to properties and deleting the mp3 file, this takes forever and i cannot see a way to do it in a batch process. Am i being stupid, is there a better way of doing this?
