Access files uploaded in one app from another app

I have one app which uses another app data as additional datastore. Is there a way to show files pdf in this app from additional datastore tables (using filedescriptor saved in additional datastore)?

Hi.
Unfortunately, there is no such mechanism in the platform.
FileStorage API works over the FileDescriptor entity, which is the part of the main data store. And there is no ability to use one entity with different data stores.
