While testing my Plex backup script, I sort of messed up the _%localappdata%l\Plex Media Server\Plug-in Support\Data\com.plexapp.system\DataItems\Deactivated_ folder. It used to contain the _Sub-Zero.bundle_, and I have a copy, but I do not remember if there were two or one levels, i.e. _%localappdata%l\Plex Media Server\Plug-in Support\Data\com.plexapp.system\DataItems\Deactivated\Sub-Zero.bundle\Sub-Zero.bundle_ (i.e. two levels: **Sub-Zero.bundle\Sub-Zero.bundle** ) or _%localappdata%l\Plex Media Server\Plug-in Support\Data\com.plexapp.system\DataItems\Deactivated\Sub-Zero.bundle_ (i.e. one level: **Sub-Zero.bundle** ). Anyone knows? Also, anyone has any idea what the purpose of the _Plug-in Support_ folder is? Is it necessary? Thanks. ---

@trumpy81 Awesome. Thank you so much. Just one follow-up question: are you saying that the _Plug-In Support_ folder non-essential for the backup? If I do not include it in a backup, would it break anything or will it be restored? ---

Heavens, no! `%localappdata%l\Plex Media Server\Plug-in Support` contains the main Plex database and a lot of various preferences. Merely the contents of `Plug-in Support\Data\com.plexapp.system\DataItems\Deactivated` may be non-essential. ---

I wonder whose idea was to place the main Plex database in the _Plug-in Support_ folder. 🙂. (This is especially puzzling in the context of the plug-in EOL that Plex announced). ---

The Plug-ins system in Plex started out as a lot more than just web scrapers for media content. Scanners and metadata agents are also (technically) handled as “plugins”. There is a lot more to it and the whole infrastructure is also already a few years old. ---

Understood, but the main Plex database (or a couple of them) didn’t start as a web scraper or a metadata agent, right? It was the core component of the application. I just find the placement of the core component in the _Plug-in Support_ folder a bit weird. Anyway, thanks for your help. I think I’m good. ---
