Yes, I also thought that. I was under the impression that the acsm are resolved in their same directory; but that was only true as long as I used to place them in "Digital Editions".

Philosophically I prefer editing extensions.cfg over koreader.app but thank you for suggesting alternatives. It seems odd to me that the loader of koreader should include the fallback to the other program.

Is user input even required if you can test for the "Digital Editions" directory? If not my initial much simpler script (now updated) would be sufficient.

I could argue that there are also social DRM books which I get via acsm, knowing a priori given their publisher that koreader opens them, but that is academic. I'd see after some use if I prefer the question for every new book, or what.
