No configuration management tool - sharing by reference

When sharing by reference, team members do not need to copy all project files to their local directories. Instead, they each have a copy of the .rpy file on their local machine. The .rpy file references the read‑only project files on a common directory. When team members need to update a file, they add the file to the local machine, make the necessary changes, and then move the updated file back to the common directory.

By using references to the common directory, files are always up to date with the latest changes. However, you might want to establish processes that prevent two developers from localizing and modifying the same unit at the same time. In addition, there is no way to track changes made to a file, or to revert to a previous version when a problem is encountered.
