The media table was originally introduced when Anki hashed media filenames, and needed a way to remember the original filename. It also helped with: 1) getting a quick list of all media used in the deck, or the media added since the last sync, for mobile clients 2) merging identical files with different names But had some drawbacks: - every operation that modifies templates, models or facts meant generating the q/a and checking if any new media had appeared - each entry is about 70 bytes, and some decks have 100k+ media files So we remove the media table. We address 1) by being more intelligent about media downloads on the mobile platform. We ask the user after a full sync if they want to look for missing media, and they can choose not to if they know they haven't added any. And on a partial sync, we can scan the contents of the incoming facts for media references, and download any references we find. This also avoids all the issues people had with media not downloading because it was in their media folder but not in the media database. For 2), when copying media to the media folder, if we have a duplicate filename, we check if that file has the same md5, and avoid copying if so. This won't merge identical content that has separate names, but instances where users need that are rare.
