If you are going to put new files on your Lenco Xemio, make sure it is in one of the following three formats:

1. MP3
2. WAV
3. WMA

If the file does not meet this requirement, the MP3 player cannot usually recognize the files.

If the files have been copied to the MP3 player, go to the '' Update Playlist '' function on the MP3 player. The MP3 player will then search for the new files. If you do not do this, the files will not be visible.
