What is a PEG file?

PEG files mostly belong to Peggle by PopCap. A PEG file is a replay clip created by Peggle peg-clearing video game. It contains a video clip recorded during gameplay. This file can be shared to other players and viewed in their own instance of Peggle. Another type of PEG file is a 2D animation project created with Callipeg animation software for the iPad. A single PEG project contains hand-drawn animation, images, and audio clips. PEG is also the filename extension of data files used by Red Faction II (now discontinued) video game.

How to open a PEG file

You need a suitable software like Peggle to open a PEG file. Without proper software you will receive a Windows message "How do you want to open this file?" or "Windows cannot open this file" or a similar Mac/iPhone/Android alert. If you cannot open your PEG file correctly, try to right-click or long-press the file. Then click "Open with" and choose an application. You can also display a PEG file directly in the browser:. Just drag the file onto this browser window and drop it.

PEG file format:

The file format, which is the arrangement and type of data in a file, determines which program can open the file. The initial characters of a file are called signature, sometimes also referred to as "magic bytes". The signature can be used to infer the file format. Nonetheless, different programs can utilize the same file extension to represent distinct file formats. Double-clicking on the file often results in an error when opening. So a detailed analysis of a file is vital in order to determine the format and the associated program. In the following you will find our evaluation of the PEG files:
