Hi folks.
I just noticed that there are 4 different locations for .src files used by the program:
%installdir%\data\sources
%installdir%\data
%appdata%\MP3tag\data\sources
%appdata%\MP3tag\data
and also 4 different locations for .mte files:
%installdir%\export
%installdir%\data
%appdata%\MP3tag\data
%appdata%\MP3tag\export</b>
This is really confusing and unnecessary from my perspective. I also noticed duplicate files.
Why not settle for a single dir for .mte and another single dir for .src ? PLEASE 
With my very kindest regards,
chrizoo
