Grouping related drawings into folders within the Project Manager helps you catalog them for easier reference. The folders you create in the Project Manager are virtual folders, defined for your project in the <project name>.xml file.
How you set up the folder structure depends on how you plan to work. If you are in a multi-user environment where everyone accesses the same network locations, you can set up absolute paths, which define specific folder locations.
If you define a folder path on a virtual drive, make sure that all project members map the network location to the same drive letter.
If you plan to transmit project files to someone without access to your network, set up a relative path. A relative path retains the project folder hierarchy when it is copied to another system.
