Hi, I want to write a program to do this, anyone can help me?

in one folder with multiple *.mp3 files, the program read each field in the mp3 id3 tag, such as title, artist etc.

then in the same folder there are respective *.tqd files for each mp3 in following format: (I am not sure what format it is, there are multiple [NUL] characters seems separate different fields)

[VT][NUL][NUL][NUL][SOH]2 Vibez[NUL]Sometimes[NUL]Cd1[NUL]12/21[NUL]...

then the program update each tqd file follow the order artist, title, disk, track...

and if that is done, the 2nd step I want to do is the reverse way, means read the text file and update the id3 tag. thanx.

I have java background, just dunno how to read mp3 file.
