Hi Megha,
Palm Treo 650 maintains a directory structure which u can follow at
the below link,
http://www.palmos.com/dev/support/docs/palmos/PalmOSCompanion/ExpAndVFSConcepts.html#1031781
The audio folder in Treo 650 contains only .mp3 files.The .mpg,.mpeg files are
present in DCIM folder.May be since audio folder contains .mp3 and hence
throwing unsupported format exception and these are the directories which are
registered at initialization.
regards
Kapil kaushik
