.CM File Extension

A .CM file is a Cable Modem Configuration File, created by Rockstar Games.

Open with Sanny Builder. Available for Windows.

What is a .CM file?

The .CM file extension stands for a Cable Modem Configuration File. This type of file is specifically used in the context of Grand Theft Auto: San Andreas (GTA SA), a popular video game. In the game, .CM files are used to create custom missions, which are additional levels or challenges that players can engage with. These files are somewhat similar to .CS files used by the CLEO script modding tool, but while .CS files contain custom scripts, .CM files contain entire missions.

To create or modify .CM files, you can use a program called Sanny Builder. Sanny Builder is a modding tool designed for making and editing game modifications (mods) for GTA games, including San Andreas. Once created or modified, these custom missions can enhance the game by providing new experiences for players.

It's important to note that .CM files are generally not meant to be manually opened or edited by most users. They are usually configured and handled by the game itself or through specialized software like Sanny Builder. Additionally, in a different context outside of gaming, .CM files can also relate to cable modem configurations, where they are used by Internet Service Providers (ISPs) to manage settings on cable modems. However, these should not be manually opened or edited either, as they are managed by the ISP.

For playing or using these custom missions in Grand Theft Auto: San Andreas, you would typically just need to have the game installed. The game itself, developed by Rockstar Games, will recognize and use the .CM files as part of its operation when these files are placed in the correct directory.
