Thomas told me that when padding with 0xff, his environment image
wouldn't be taken into account anymore.
I'll add the option anyway, but do you know what could be happening ?
Also, I guess this makes necessary making sure there is a \0 after the

I wasn't sure whether the proper way of doing it was "read/write 1 byte,
N times" or "read/write the size of the file, 1 time". I probably
