External Assets

Easily share assets between Unity projects with this integrated file and folder synchronization tool.

Drag external files to the External Assets editor window to add them to your project. They are then synchronized and updated when changes are detected, either manually or automatically.

Supports 3 modes of synchronization:
Synchronize Changes and deletions are copied from source to project, and vice versa.
Echo: Changes and deletions are copied from source to project, but not the other way around.
Contribute: Changes are copied from source to project, but nothing is ever deleted (unless you do so manually)
