Watch folders for deleted files and delete from Nextcloud

[Terrox]

Is your feature request related to a problem? Please describe.

Currently I can use Markor to edit notes and those are synced when I open Nextcloud Client and sync the folder. But If I delete a file outside Nextcloud Client that file will just be restored by Nextcloud Client sync.

Describe the solution you'd like

A watched folder like the AutoUpload folder which will also delete files.

Describe alternatives you've considered

Syncthing

Additional context

I would use this to handle external note editor app syncing so I can delete a note via native android methods or 3rd party app without having to delete in the Nextcloud Client app.

GitMate.io thinks possibly related issues are #2281 ([Deleted]), #2382 (Delete multiple files), #975 (Showing deleted files), #2574 (crash on file delete), and #1048 (Nextcloud android app does not move or delete original files).

If you click "sync" on a folder it performs a 2-way sync, so yes this is intended.
For your special case you could manually add an auto upload folder, but then you will still have to delete the files locally.

Also, with 3.5.0 of the Nextcloud app, in case https://github.com/gsantner/markor would make use of the document provider implementation this would all work out-of-the-box and also instantly.

@AndyScherzinger Where is the spec for that?

[AndyScherzinger]

@tobiasKaminsky can you answer this question? :)

[tobiasKaminsky]

@Terrox what do you mean with spec?
The Document Provider is supplied by Android's SDK: https://developer.android.com/guide/topics/providers/create-document-provider

Usage is to use an app that can open files from document storage provider and then browse to NC's files and use them.

@tobiasKaminsky I mean I don't know much about this but I'd like to make the Markor guy's job a bit easier with a reference :) .
