What is an ATG file?

ATG files mostly belong to ActivInspire. The ATG file is mainly an ActivInspire flipchart file. This file holds interactive lesson data used in digital whiteboard systems. It stores multiple pages with text, graphics, and annotations that form complete flipchart presentations.

Interactive Lessons: Contains pages that display text, images, and drawings for classroom activities.
Content Storage: Organizes multimedia elements in a structured layout.
Autosave Function: In some cases it works as an autosave text graphic file that may be generated by ATutor systems.

If you have an ATG file, open it with ActivInspire. For versions linked to ATutor, check details via the ATutor website.
FilExt.com note: Few users know that these files carry metadata to help recover unsaved edits if a crash occurs.

How to open an ATG file
