In the further part of this page we have added a list of programs that should open your MPGINDEX file. It is enough you choose a proper application for your operating system, download and install it.


The file extension MPGINDEX is used for the index files of imported MPEG video files from various Adobe media-processing products. MPGINDEX files are automatically generated files that are created when importing or adding an MPEG video file to a project.

Above all, this measure is intended to ensure faster work with the preview. In addition, such an MPEG video file must be checked only once.

Depending on the file type, the program creates various auxiliary files (cfa, pek) in the media cache. In addition, a media cache database is created on the specific Adobe programs can share. This gives the programs access to the media caches of the other programs. (if available)

In fact, MPGINDEX files are created by the Adobe Media Encoder, a software component that is part of almost all media-processing Adobe products.

You can create or clean up cache folders under 'Edit-> Preferences-> Media & Disk Cache' (Windows) or 'Settings-> Media & Disk Cache' (Mac OS). These files are only necessary during a project and can be deleted after completion.

How to open a MPGINDEX file? Advice and guidance

Absolutely most often appearing reason that prevents you from opening the MPGINDEX 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 MPGINDEX 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 MPGINDEX files. At this point we are looking for disk space where the application was installed in and we can link it with a MPGINDEX file. Since then, our operating system will use the selected program to support all MPGINDEX files.

Other issues

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

- verify that the MPGINDEX 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 MPGINDEX 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.
