I have transferred WMA files to the E-100/E-105, but Mobile Audio Player doesn show them or won let me add them to the playlist. Why?
A. The WMA files must reside in either the \My Documents folder or the \Storage Card\My Documents folder on the E-100/E-105. If you have placed WMA files elsewhere on the E-100/E-105, move them to one of those folders, then open Mobile Audio Player and click the Add button to add them to the playlist.
