Feature description

When a folder is shared in read only mode and synced to the desktop and locally a file is copied into this read only folder the client continuously tries to sync the file.

As the client knows that the folder is read only there is no need to try this.

Proposed solution

The local file shall be kept as local file - maybe with a different overlay icon.
Client shall not try to sync it.

Once the permissions change these files can be uploaded again.
