Open file from URL locally if desktop client installed

A lot of users use NC as a way to sync and exchange their files on their desktops without much interaction via web preferring local apps (Text/Sheet processors etc).

In my case users need to exchange the files located in group folders. NC provides internal URLs of the files/dirs. So users copy these URLs in their Windows File Explorer and send them via messengers/email whatever to their counterparts. Counterparts click on the URL and are proceeded to NC webUI to open folder or file. This is not always convenient.

My suggestion is to provide an option to open files and folders locally on their devices, providing they:

1. have NC desktop client installed, working
2. they have permission to open file or folder
3. they have an app to process this type of file

This option may be listed as a separate item in a NC desktop client dialogue when clicking over file or a folder which is synced, or as options in the NC desktop client itself, eg: Always open locally/Always open in web/Ask each time.

NC itself has a function Edit locally, which is accessible under 3-dot manu in Files app, which allow to open a file on the device in case there's NC desktop client installed. As I understand the main task is to make NC desktop client be registered as a processor of all URL requests to NC files app in order not to open web browser each time.

What do you think about that?

Start with the Files app's existing “Edit locally” action and the desktop client's handling of internal file and folder URLs. Review how the proposed permission, client-installed, and local-application conditions would interact with the suggested “Always open locally/Always open in web/Ask each time” choices. Done would require an agreed design and behavior for opening eligible URLs locally without breaking web access.
