User SerVB made a script to care about moving files into the Syncthing folder until N movie episodes are present.

See syncthing#1279 for more details on the idea.

Thanks for your contribution!

# "Sequential Mover":
# The script for moving a few episodes from the source dir to the syncthing "dist" dir.
#
# This script uses a json config file. Here is the example:
# {
#     "source": "D:/series/",
#     "dist": "D:/_syncthing/_few_episodes/",
#     "count": 2,
#     "exceptions": [
#         "Chaos - A mathematical adventure",
#         "Miraculous Ladybug Webisodes"
#     ]
# }
#
# The script assumes that subdirs of the "source" dir are different TV-series.
# Then it treats all the files in "TV-series" dirs as episodes.
# Example:
# D\
#  +-series\
#          +-series1\
#          |        +-series1-e1.mp4
#          |        +-series1-e2.mp4
#          +-series2\
#                   +-season1\
#                   |        +-series2-s1e1.mp4
#                   +-season2\
#                            +-series2-s2e1.mp4
#                            +-series2-s2e2.mp4
#
# The script searches for the same series in the "dist" dist dir and determines how many episodes to move.
# Assume "count" = 2. After script run, the "dist" dir will look like this:
# D\
#  +-_syncthing\
#              +-_few_episodes\
#                             +-series1\
#                             |        +-series1-e1.mp4
#                             |        +-series1-e2.mp4
#                             +-series2\
#                                      +-series2-s1e1.mp4
#                                      +-series2-s2e1.mp4
#
# If you rerun the script again, it will do nothing, because there are already two episodes moved.
# If you remove episodes from the "dist" dir, the script will again move episodes filling up to "count".
#
# Also, the script removes empty dirs from both "source" and "dist" dirs. So the "source" dir will look like this:
# D\
#  +-series\
#          +-series2\
#                   +-season2\
#                            +-series2-s2e2.mp4
