I tried to modify the mimemap file as you suggested but actually as you 
say, the download does not work better.
I investigated in !NetSurf, it will look for the mimemap file but ignore 
these additions? even after restarting.

I just did a test with my windows pc. I take a Rhapsody file, I change the 
file to T and add the suffix / Rhaps4.
Then I open LanMan and copy the previous file to the destination 
directory, and there the file appears with the correct icon and the 
correct file type...
The same test with a maestro file, file type modified in Text, the 
conversion is not done ...
I checked the mimemap file and added the following line in the Application 
topic:
  application/x-maestro Maestro  af1 ,music
But unfortunately it does not work. By checking the list of applications I 
found a line:
     application/riscos    *     *
I commented it out and in this case it worked. Ouf!
But unfortunately no change with NetSurf.

I think this is the right solution, thanks for your reply.
