The _Shortcuts folder is used to store all data shortcuts for the entire project. This allows all team members to easily reference project data from a central location.

Data shortcut XML files are automatically saved in the _Shortcuts sub-folders by Civil 3D and contain the DwgRelPath tag which enables them to be used in a shared environment. When a data shortcut is created locally, the associated XML file must be uploaded to the appropriate _Shortcuts sub-folder on the FTP or cloud-sharing site.
