Saving a project is done via the File menu. Only two file formats are available: GS and GSZ.

The GS file format is actually a set of files stored in a folder named after the GS file. Inside this folder, the file graph.xml contains the project’s scene graph, the folder META-INF holds meta information, and any additional files included in the project are saved within this folder or its subfolders. To avoid conflicts between different projects, it is mandatory to use a separate folder for each project.

Please note that saving a project will not automatically save changes made to text files within the project. These files must be saved separately.
