How do I tell Plex to skip certain folders, but to leave the library items in them unchanged?

Library scans are painfully slow, and being able to tell it to skip 2,000ish movies would be most useful.

Library Refreshes are slow. But you practically never need to refresh a whole library’s worth of media.

Library updates are not slow - particularly if media files are organised the right way.

  • Avoid over thousand files in one single folder
  • Don’t let other software (SubZero and/or other media ‘catalogs’ & players) rummage around in your media folders, thereby changing the ‘changed at’ time stamp of your files and folder. Plex will jump quickly over folders which were not changed since the last library update. But if other software changes anything in there, a time-consuming full scan will take place.
  • if you have more subfolders, necessary full scans are limited to the small subfolder which was actually changed. So if you switch to the model ‘one movie - one subfolder’, scans are faster. This approach has also advantages if you use external subtitles and local extras as explained in this post.
