What is an I7X file?

An I7X file contains source code used by Inform, an IDE for creating Interactive Fiction (IF) programs used by Z-code interpreters, such as Zoom or Frotz. It stores code for an extension that extends the capabilities of Inform, such as interface upgrades or IF story creation capabilities. I7X files are saved in plain text with Unicode UTF-8 encoding.
