A connected drive is a local folder that mirrors the structure of the connected data source.
The following image shows a connected drive for Fusion 360 on Windows®.
While the structure is replicated in the connected drive, the files are not downloaded until they are opened.
You can open and add files through the connected drive, similar to how you access and modify files and folders using Windows® Explorer on Windows® or Finder on macOS®. The changes are replicated in the data source.
This functionality allows you to manage data or update folder structures without having to launch the data source application.
