Help with microSd card and playlists on Sansa e250

I have a Sansa e250 (2GB) version 1 and I added a 2GB microSD memory card. When I connect it to my Windows 7 PC in USB mode = MTP, windows properly recognizes it as a sansa mp3 player, but only shows me the main 2GB as available memory.

If I switch to USB = MSC, Windows explorer shows me 2 separate memory devices of 2 GB each: the sansa itself plus the MicroSD card and it does not recognize it as an MP3 player device.

I have a playlist in Windows that points to music files in subdirectories under “My Music”; the total size of all files referenced in that playlist is 3.5 GB.

Is there an easy way to import (synchronize) the windows playlist and files with my sansa 250 + microSD card so I use all the capacity?

Can you describe steps to accomplish this?

Thanks
