What is a .aetx file?
The .aetx file format is a binary project file used by Adobe After Effects.

Unlike the older .aep format which is text-based, .aetx is optimized for faster loading and smaller file sizes. It's essentially the native working file for After Effects, allowing you to save your progress and continue editing complex animations and visual sequences.
