Have you encountered a problem with a AEP file? Don’t you know which program opens a file with this extension? You will find all the information you need about working with a AEP file here. In the further part of this page we have added a list of programs that should open your AEP file. It is enough you choose a proper application for your operating system, download and install it.


The file extension AEP is used by the video compositing and animation software Adobe After Effects for project files. In addition to references to videos, audio files and images, AEP files also contain cut and timeline information and effects settings.

Usually, the paths to the media files are also saved, so that they are only found if they are in the original directory. But you can also load AEP files and specify new locations for missing files.

It should be noted that AEP files are usually not backwards compatible, so with the CS4 version, for example, no CS3 compatible AEP files can be created.

How to open a AEP file? Advice and guidance

Absolutely most often appearing reason that prevents you from opening the AEP file is the lack of a proper application to support it in your operating system. It is notably the first thing you need to address. When one of the programs to support a AEP file from the list is already installed, you can try to rerun the file. The system should display a message asking you to choose a primary application to support AEP files. At this point we are looking for disk space where the application was installed in and we can link it with a AEP file. Since then, our operating system will use the selected program to support all AEP files.

Other issues

Despite the described problem with AEP there may be many more problems. If the existing operations were not effective, get involved with the following matters:

- verify that the AEP file is not damaged and that it has been downloaded or copied in whole
- verify that the file has a file extension that has not been intentionally changed (for example, if it do not contain other information than its extension suggests)
- make sure again whether the AEP file type is linked in the operating system with a proper program
- make sure that the file is not infected with a virus and you have up to date software and drivers.
