The problem:
Sometimes you need to delete things to make more space. Deleting big things gets space back faster.
If you store movies in folders, windows can’t easily sort folders by the filesize of their contents, which makes it hard to figure out which movies might be hogging space due to inefficient encodes or multiple redundant versions of a video. Some tools can figure this out for you (e.g. SpaceSniffer) but they can be very slow especially when your library folders are on a slow NAS.
The solution:
Plex knows the filesize for all indexed videos, and allows you to delete files directly from the web app. Plex allows you to sort by other metadata like date added, resolution, duration etc - but not filesize. If filesize was added to the list of sort options within a library, we’d have an easy way to identify and clean out or re-encode large files.
