An ERP file may also be an archive used by games that utilize the Ego game engine, such as Race Driver: Grid, Colin McRae: Dirt, and F1 2016. It contains multiple asset files, such as .TGA , TGA.SAMPLER, and TGA.IMAGE files, which are used to store textures for objects in the game.
More Information
ERP files are typically only seen by gamers who are modifying the gameplay of a game. Ego ERP Archiver is a popular program for opening ERP archives. Users can then export graphic files stored in the archive, modify the exported graphic files with an image editor, then import them back into the ERP archive.
NOTE: The Ego game engine is developed by Codemasters.

More Information
Encarta was a CD-ROM based encyclopedia and dictionary published by Microsoft from 1993 to 2009. It was birthed in the pre-Internet 1990s and was used as a digital reference, most commonly for work and school projects. The program contains articles, pictures, illustrations, videos, sounds, and animations. Encarta eventually met its demise because it couldn't compete with free online encyclopedias like Wikipedia.
