What is an INFORM file?

Inform is a free application that provides tools for creating IF stories that other users can experience. When simulating a story, users can control characters with text commands and modify the environment.

Inform users can create stories and save them as INFORM project files. These files allow users to save, close, and re-open a project for further editing.

To create an INFORM file, select File → Save or Save As..., name the file, select the save location, and click Save.

After you complete your story, select Release → Release to create a .ZBLORB file that can be uploaded to the Internet and shared with other users.
