Unit Type Data files have an extension of .ctu.  Using the dialog box, navigate to
the desired folder, type in (or select to overwrite) the desired file name and click Save.
This will save all Unit Type data in the current drawing to the selected file. This allows
users to organize Unit Type data by client, zoning district, permitting jurisdiction, etc. 

It is not recommended to store Unit Type data files in the Land Planner Suite
install directory.  These files should be stored with project data files to insure
proper back-up and security.
