Preview Generator generating previews for Joplin .md files

[/details]

Nextcloud version 13.0.4
Operating system and version Rasperian Stretch)
Apache
PHP version 7.0

The issue you are facing:

Is this the first time you’ve seen this error? (Y/N): Y

Steps to replicate it:

  1. Simply use Joplin with Nextcloud
  2. Enable Preview Generation

I run a cron job to regularly generate preview files. I run the command with the verbosity paramater so I can see what’s being generated. I noticed it is generating preview files for my Joplin note files ending in .md

Here is an example output from the preview generate command:

2018-06-29T18:00:29+00:00 Generating previews for /xxx/files/Joplin/a6a85747fa79482b88a3705881c1d35.md

Generated image files take up a lot of space and I would think it unnecessary to generate preview files for the Joplin files since one never actually looks at the encrypted .md files. I view the Joplin notes using the Joplin apps.

Thank you.
