The Open command allows you to read a previously saved project.
The program will read the corresponding Project Data File. Starting with version 4.0 of the Spiral program, the Project Data File is a binary file that can no longer be viewed or manipulated outside the Spiral program. Use the Import command to import project data created with previous versions of the Spiral program or with the Export command. The default extension for Spiral project files is .spiral. The command then displays the Open dialog window, which is illustrated below in Figure 5.4.
As all applications using the Scientif support library, the Spiral application can only open one project at the time. If there is a project currently open and if it has been modified, then the program will display the Save Changes dialog window and ask if you wish to save those changes, discard the changes, or if you wish to abort the opening of another project or the creation of new project. The Save Changes dialog window is illustrated in Figure 5.2.
However, you can still compare two projects side by side by opening a second copy of the Spiral application itself, opening the second project with this copy of Spiral, and then arranging the two application windows on your desktop.
