Guide to Directory Splitting in Unraid

How the new directory splitting in Unraid works:

The share itself is the top level
Top level means anything contained INSIDE the top level folder will be potentially split up. Nothing beyond that level will be split further.
Top two means anything INSIDE the second folder in the structure will be potentially split up. Nothing beyond that level will be split further
And so on.

       (\share\)
            ↓                
Example: \Movies\Movie1\Movie1.mkv

Split only the Top Level:
        (Splits folders at this level apart from each other)
                              ↓
Disk 1 may contain \Movies\Movie 1\All Movie 1 files
Disk 2 may contain \Movies\Movie 2\All Movie 2 files

Split only the top two:
                               (Splits Here)
                                     ↓
Disk 1 may contain \Movies\Movie 1\some of the files for Movie 1
Disk 2 may contain \Movies\Movie 1\some of the files for Movie 1

for TV Shows:
        (\share\)
            ↓
Example:\TvShows\Tvshow 1\Season 1\Tvshow file(s)

Split only the Top Level:
           (Splits folders at same level as this)
                               ↓
Disk 1 may contain \TvShows\Tvshow 1\All Seasons\All Tvshow 1 files
Disk 2 may contain \TvShows\Tvshow 2\All Seasons\All Tvshow 2 files

Split only the top two:
                           (Splits folders at this same level)
                                         ↓
Disk 1 may contain \TvShows\Tvshow 1\Season 1\All Season 1 files
Disk 2 may contain \TvShows\Tvshow 1\Season 2\All Season 2 files

Obviously, you need to adjust if you have more folders than that. I have my folders set up as follows:

Share is \movies\ - Split on top two directories

         (Splits here)
                ↓
\movies\Adult\Movie 1\All Movie 1 files will be on the same disk 

and

Share is \tvshows\ - Split on top three directories
                    
                     (Splits here)
                           ↓
\tvshows\Adult\tvshow 1\Season 1\All season 1 files will be on the same disk. (season 2 could be on another disk)

This is my setup by the way with the same goal (All movies files from movie 1 on same disk, different movies can be on different disks. All episodes in a season on same disk, different seasons can be on different disks)
Share is \movies\ - Split on top two directories
\movies\Movies\Movie 1\All Movie 1 files will be on the same disk
\movies\AnimeMovies\Movie 2\All Movie 2 files will be on the same disk
\movies\Movies4k\Movie 3\All Movie 3 files will be on the same disk

Share is \tv\ - Split on top three directories
\tv\TV\Tvshow1\Season 01\All Season 1 files will be on the same disk
\tv\Anime\Tvshow2\Season 01\All Season 1 files will be on the same disk

Fixed my example, Thank you.
