What is a .aepx file?
An .aepx file is an XML-based project file for Adobe After Effects, a powerful motion graphics and visual effects software. Unlike the standard .aep file, which is a binary format, .aepx files are human-readable and can be edited with text editors, though this is not recommended for complex projects. They store all the information about your composition, layers, effects, and timeline, allowing you to resume your work or share project settings. This format is primarily used for project interchange and version control.

Common Problems with .aepx Files
Frequently Asked Questions
No, .aep is the standard binary project file for After Effects, while .aepx is an XML-based version that is human-readable and better suited for version control and scripting.
Yes, technically you can open and edit an .aepx file in a text editor because it's XML. However, this is strongly discouraged unless you have a deep understanding of the file structure, as incorrect edits can easily corrupt the project.
No, .aepx files, like .aep files, do not contain the actual media assets. They contain references to these assets stored elsewhere on your system.
Technical Details
.aepx files are structured as XML documents, making them inherently text-based and parsable by machines and, to some extent, humans. This XML structure describes the complete project, including assets, composition settings, layer properties, effects, and keyframes. While it offers benefits for version control and scripting, it's not a container for media assets themselves, only references to them.
