DVDs, Blu-Rays, and the two UHD Blu-Rays I have are all mixed together. Video games are separate, and those are further separated by console (PS3 vs PS4 - if the PS4 was backwards compatible I’d mix them the way my movies are).
Alphabetical by title, including TV shows. Series are grouped together, alphabetized based on the “series title” (that is, the Bond movies are under “J” for “James Bond,” the Hobbit and LOTR movies are under “M” for “Middle-Earth,” and then you have your “standard” ones like the Bourne movies under “B”).
I rip all my movies and put them on KDLinks HD720 media player (with a 6TB HDD inside). Movies and TV shows are in separate folders.
Movies in a series are labeled like this:
Marvel (01) (Iron Man)
Star Wars (04) (A New Hope)
That way the series all stay together. Remakes have the year in parentheses, and anything that isn’t the original theatrical cut has that in parentheses as well - so, “Blade Runner” is now “Blade Runner (01) (Blade Runner) (Final Cut)”.
TV shows are broken down into season folders within the series folder, with the year of each season being in front. Movies that are part of a TV show’s continuity are in the show’s folder within its own folder. So X-Files, for instance, goes:
1997-98 - Season 5
1998 - Fight the Future
1998-99 - Season 6
And so on.
I use numbers instead of years for the season folders if necessary (like my Clone Wars folder, which is in chronological order rather than broadcast order).
I think that’s about it…
