 Movies should usually be in the library root directory or in a subfolder for the individual films. The subfolders allow for organization of metadata and images. Adding the year at the end in parentheses will yield the best results when scraping metadata.

+## Multiple Versions of a Movie
+
+Multiple versions of a movie can be stored together and presented
+as a single title. To accomplish this each version of the movie needs to be located in the same folder and the file name needs to start with the name of the folder as seen below.
+
+```
+    Movies
+    └── Best_Movie_Ever (2019)
+        ├── Best_Movie_Ever (2019) - 1080P.mp4
+        ├── Best_Movie_Ever (2019) - 720P.mp4
+        └── Best_Movie_Ever (2019) - Directors Cut.mp4
+```
+
+To distinguish between versions each filename needs to have a space , hiphen, space and then a label. Labels are not predetermined and can be made up by the user.
+
+Additionally, labels can be placed between brackets with the same result as seen below.
+
+```
+Movies
+└── Best_Movie_Ever (2019)
+    ├── Best_Movie_Ever (2019) - [1080P].mp4
+    ├── Best_Movie_Ever (2019) - [720P].mp4
+    └── Best_Movie_Ever (2019) - [Directors Cut].mp4
+```
+If labels are not added to the end of filenames as shown each file will be treated a unique movie and not a multiple version of the same movie.
