Have loaded music onto Walkman in a folder , when I tried to transfer back to PC at a later date the folder had a totally different content , the files shown existed on Walkman but in a different folder , the original folder content still plays correctly and if I display on Walkman it is OK , but in explorer it is wrong !!!!!!!!
You might be able to see a few different folders and was trying to open the folder different to what you are looking for. Check this out and see what folders uses by default.
