Hi Pierre,
if you open a file, e.g. something.png, and then save_as with having the file type selection set to e.g. JPG, MP correctly adds the .jpg extension.
It does not remove the .png extension, though. This gave me a lot of files called something.png.jpg or the like.
It's common practice to remove the previous file extension when a program writes the same file to a different format.
Regards
Dietmar
Wish: Remove extension from filename when saving to different format
