It appears the preview-generator app generates previews for non-image files. This makes no sense. It is generating previews for joplin *.md and *.txt files. These are not image files. I know this because I log all files using the verbose mode and these files are showing up in the logs.
I understand one can exclude the gallery from generating previews by adding a .nomedia file to the folder. Will this also work for the preview-generator?
Is there an option to completely exclude one or more selected folders from preview generation?
