axesFlip Designer uses the .flip file format, officially called the axesFlip Template Archive, to store templates.
An axesFlip Template Archive is a ZIP‑based package that contains the JSON definition of the template along with any additional files required by the template.
By bundling all related content into a single ZIP archive, the .flip format makes templates easy to share, version, and manage, while ensuring all necessary components remain together.
The JSON file inside the archive defines the template’s structure, nodes, properties, and expressions.
