Hello there! I have been happily creating custom decks, but ran into some trouble when trying to export a deck that includes in the template on the front and back a file in the media.collection folder called _sound.mp3 file. On import of the exported deck, this file is missing from the collection.
I tested export and import of a file called _image.png placed in the front and back of the template and it does export and import with the deck, however, the _sound.mp3, does not.
I am exporting an Anki Deck Package (.apkg) file.
I am hoping that I do not need to create an extra field to place my small sound file into.
