the app seems not to recognize files made available by nextcloud app "groupfolders"

[nielsson4711]

Referring to @chrros96 reply & question from last year:

The app scans files only once - even if the folder or file is shared with a group or one or more users. The only exception of this statement occurs on files that are mounted via external storage. Or are you referring to something other than sharing by the term "group folders"?

app "groupfolders"
The app "groupfolders" enables for physically storing a set of files at one certain location - outside the nextcloud users "file" location - and provide this set by reference towards a group of users.
App: https://apps.nextcloud.com/apps/groupfolders
Code: https://github.com/nextcloud/groupfolders

effect for users
Users who are members of the group assigned to a "groupfolder" will see the folder in the "Files" app with all its contents. However, the contents of the folder are not in the user's storage area, but below ${NEXTCLOUD_DIR}/data/__groupfolders/

suggested feature extension
If the app "duplicatefinder" could differentiate folders from the app "groupfolders" from ordinary folders, it would

• not consider to look after groupfolder files and therefore not throw the error message
  "The given path does not exist (groupfolder file path)" on group folder content;
• offer an option to index one and/or all "groupfolders";

P.S.: I'm not yet fluent enough in nextcloud development with PHP and container debugging to provide a feature extension on my own. But i'll gladly assist.
