After you have completed your Didger project, you can save the information in a Didger project .PJT file. Project .PJT files save all the project information such as calibration information, projection information, all digitized or imported objects, and object properties such as line color, and the IDs associated with the objects. Although the .PJT files cannot be used in any other applications, these files preserve the Didger data so you can recall the file later, allowing you to add additional data, to edit any exiting data, or export the data to a file that can be used in other applications.
You can use File | New to create a new project file, File | Save to save a project file, and File | Open to open an existing project file.
