Is there any way to play all files in a directory by one url?

Hi all,

I am testing fms this days, I have put all my files(such as 1.mp3,2.mp3...n.mp3) in my directory.

I can play single file fine with url like this:

rtmp://localhost/mp3/mp3:x/2

but i want to know is there any way to play all files in my direcotry?

for example, user click the play button, the player(smp) automatic plays all files in the directory, link windows media server.

Should I use playlist? Or there is another better way?

Thanks a lot.
