Hi Damien, since I have you here, let me first thank you very much for your work on the Anki suite, I use it (literally) every day.
Back to my question - I’m pretty sure that the media was in sync because I do it often, but somehow the _ files are still there. Is there anything that I can do now (can you provide steps?), or is it at this point broken beyond repair and I will never be able to get rid of them?
