    I've noticed that, for example, one game will have its model/image files in a format like:

    Soldier.mimg

    And another will have something like:

    SoldierAnim.animimg

    But how exactly, per se, do they do this and why? Is a standard image-extension or format bad entirely? I mean even if it's to encrypt/protect the data from being changed, it can still be changed.

    And I notice that mainly only do professional video game companies do this, and amateurs/indies may not, unless it's a serious project.

    Well I know on Linux and Mac, file name extensions aren't required. That's why you can copy files and just name them "something.backup" I believe it's just however they want to name it. I'm not certain how this translates into Windows, but at least that's how it works on UNIX.

    File name extension is one thing, but an actual format that the file is translated in to is what I question.

    Many companies both encrypt and change the format of their files and file data.
