GetPlexSyncedItems.ps1

# Basic script to copy and properly rename Plex synced files on Windows
# Made because of a bunch of limitations between plex and windows and chromecast
# 1. Plex Windows app wont cast to chromecast
# 2. Plex Web app will cast to chrome cast but wont access local synced content
# 3. Plex Web app will download but not transpose
# 4. older chromecast does not support x265 decoding, so needed transpose
#
# Plex stores the transposed synced files in a non-user-friendly manner using GUIDs as subdirecotries and all files are called "File.*"
# This script finds the files and extracts the associated metadata, creates a friendly filename and copies to the specified destination.
#
# limited testing, no warranty/support. Use at your own risk.


# Set $destination to where you would like your files to be placed
$destination="C:\PlexFiles"

# If you have not moved you synced items in the Plex windows app Settings this should work as is
#If you have moved them update relevant paths, taking care to retain necessary subdirs, it should point to valid sync directory.
