What is an .AEX file?

.AEX is After Effects Plug-in

An AEX file is a plug-in used by Adobe After Effects and Premiere Pro, which are professional video-editing applications. It stores content that extends the functionality of the After Effects application, such as support for camera raw files or video filters. AEX files are written in the C/C++ programming language.

Several plugins come installed with After Effects. However, they may also be created and sold by third-party developers. You can install a plug-in to extend the functionality of After Effects by placing it in the plug-ins folder.

AEX plugins are stored in the following directory:

  • Windows - Program Files\Adobe\Adobe After Effects (version)\Support Files\Plug-ins
  • macOS - Applications/Adobe/Adobe After Effects (version)/Plug-ins

You may have to restart After Effects in order to use a newly installed plug-in.
