Emulate a portable device in your computer

Hi,

i'm new, and know what i'm going to tell is not in the way you are working (and may be is done).

Every day there are more devices (TV, DVD players, HiFi and car Audio, ...) where you can plug a portable Device (usually an USB memory) and access to files and play the music, or video you have there.

may be interesting an application than let you select a folder in your computer, and emulate your computer is an USB memory, so you can connect your computer and this device using USB cable, and this device can play the files in the selected folder in the computer.
