Making resources available in a project folder (and vice versa): duplicate, replicate, something else?

I’ve got several projects which I’m working on via Google Drive or OneDrive. We’re using that to share project files and resource materials. Some of these materials I also want to keep in my own database. And the other way around: some materials in my own database I want to share with co-workers as part of the background materials for the project.

Curious to what other are using to achieve this, here’s what I’ve come up with:

  1. Index and duplicate - my main ‘gripe’ is that I often use Classify to quickly put items in the right group, but it only allows ‘move’ or ‘replicate’ (I could possibly try scripting something to change this)

  2. Index and replicate to my own database (chances are someone deletes the original at one point). Problem with replication is that co-workers obviously don’t see the replicates as files in a (shared) folder so replication only works when I replicate from the shared folder to my database.

Interested to see what scenario’s people are using where you have reference materials that come along in a project that you want to keep, or materials you’ve gathered that you want to make available to others (or just put in a project folder)
