misc questions

[loophead]

Hey gang,  just moved from a TASCAM MP-GT1 to the MicroBR.  I have a couple of questions I counld not seem to find searching the forums:

1)  anyway to organize the MP3 music in folders?  I have a **lot** of MP3s I want to download and use for backing tracks and training.

2)  anyway to view the entire filename of an MP3? 6 letters is too little.

3) is there a way to temporarily turn on and off the A<>B looping, without it loosing the setting?

4) lastly, anyway to review the song while using FF and REW?

THANKS!
