Sony nwz-s636f has a mind of it's own!!
My wifes 636f accepts file transfers fine (mostly mp3's), but lately seems to be deleting files after she has transferred new ones to the player.
She is using Realplayer of all things because she says it's the only software that shows her a playlist of her music and on the left hand tree menu her Sony machine so can can drag the files there.
I checked the player with Windows Explorer and in addition to the main "MUSIC" folder there are many "Music" folders, some with mp3's in them and others that are empty. She and I have no idea how they got there. Should they be deleted ? Would they be confusing the software ? Does anybody have any idea why files are getting deleted after new music is transferred to the player ?
