Per another thread ( https://emby.media/c...ry/#entry484965 ) video files that do not have an external ID (eg, TheMovieDB, IMDB) associated with them in Emby will lose their Watched status if you ever move the files to another location. This is because currently the only way to determine the uniqueness of the file (if it does not have an external ID) is to use the full path to the file.
Now, most items will have an external ID, but the big exception can be Movie Extras and TV Specials. Some TV Specials will have an external ID. And some Movie Extras do exist in the IMDB and TheMovieDB, but currently there is no metadata lookup available for Movie Extras ( https://emby.media/c...kup-for-extras/ ). So if a Movie and it's associated Extras is ever moved, the Watched status for those extras will be lost.
This feature request is for there to be some better method of identifying files such that those files which do not have external ID's can still be correctly identified (and thus Watched status preserved) even if they are moved. I am most interested in this for Movie Extras.
I'm not sure what the best route for achieving this would be, but wanted to put the idea out here for consideration.
