I had moved files from Itunes to a file on my computer
. Later I used Windows Explorer to copy those files to my Zen Nano 512 MB player. When I tried to play the songs, it only found one. I hooked it up to my computer and deleted that song. Then the screen said NO MUSIC
. I tried Recorded Tracks but it says NO RECORDINGS. I reorganized all the tracks into a folder. This is similar to how I had organized my music a few months ago when everything worked OK. Windows Explorer calls these files System Files. I used Windows Media Player to classify all of them as MP3. That's how they were stored in Itunes. I still get the NO MUSIC message. Any suggestions would be greatly appreciated.
