The Editor saves and loads project files with .apj extensions.  Such files contain proprietary binary representations of the operational aspects of Absyntax projects.  These files are also used by the Batch Client.

 

When the Editor saves a project, it also saves the project workspace in a separate file with a .apw extension.  A project workspace contains details such as project settings, the location of features on the design surface and the shape points of connections between connectors.  Workspace files are only relevant to the Editor.

 

The Editor can load a .apj file without an accompanying .apw file but the project's content will not be presented as its creator intended.  If you come across this situation, use the Auto Layout facility.

 

In general, though, if you are sharing projects then it is good practice to keep .apj and .apw file-pairs together.
