What does "Synchronize Working Directory" in RStudio Files > More ... do?

In RStudio (Version 2024.09.1+394), there is an option "Synchronize Working Directory" in the Files pane under More. It seems to toggle a state since choosing it alternately adds or removes a checkmark, but I can't find any documentation or web posts.

I am curious because I am trying to figure out "idiot-proof" control of R's working directory for teaching purposes. (I have already found the here package and project-oriented workflows.)

Thanks for any help!

AFAIK, if ON, it updates the Files pane to show the current working directory if it is changed with setwd().
