.map File Extension

Developer: id Software
File type: Quake Engine Map File
You're here because you have a file that has a file extension ending in .map. Files with the file extension .map can only be launched by certain applications. It's possible that .map files are data files rather than documents or media, which means they're not meant to be viewed at all.

what is a .map file?

These files are called Quake Engine Map Files that refer to uncompelled game maps used by the game that Quake engines develop. These MAP files were developed by id software and are saved in a text format that humans can read. MAP files can either be a binary map file compilation used for Half Life and Quake games. Several map editors can be used to create MAP files like the Valve Hammer Editor, a program used to compile the map targeting it to BSP format. MAP files are also used by's Torque Constructor and they are used to transform maps to DIF formats that contribute to its development. These files can also be used for Torque games, targeting several platforms such as PC, mobile and console. MAP formats are used by numerous game engines like the Quake engines, Goldsource Engine, Unreal Engine, Torque Engine and Dark Engine. MAP files can be saved in newer VMF formats with the use of Valve Hammer Editor 4, a program previously called "Worldcraft”.

how to open a .map file?

Valve Source SDK

Valve Source SDK

Valve Source SDK is a software development kit or SDK software, which is created by Valve Software, that is designed to create mods and maps for Source engine, except for some game applications like Portal 2, Left Dead, and Alien Swarm, as they have their own SDKs already. Source SDK has four main utilities and these are to create a mod, refresh SDK content, reset and edit game configurations. In creating a mod, it dumps the code of Source engine into a folder and a mod directory is created under the folder called SourceMods. SDK content is refreshed by checking new data updates as well as downloads. Game configurations can be reset and edited too. Basic games are the basis of how game configurations are recreated, while mods in configurations are removed except if they are edited manually. There are also applications integrated in this kit software, which are Face Poser, Valve Hammer Editor or Hammer and Model Viewer.
Valve Hammer Editor

Valve Hammer Editor

Valve Hammer Editor is a map creation software for games, engines and other sources of Valve Software, This is also called as Hammer, which was more popular as Worldcraft, its original name, that is developed and launched in the year 1996. This is downloadable for any source based game that is part of source SDK or a first person shooter game. Before the Source engine, brushes, which are a set of simple primitives, were the only construction blocks in Hammer Editor, but still usable in older versions of GoldSrc games. This software saves a level life in many format types, which include in the binary and proprietary, text based or .rmf format, human readable .map format, and .vmf format, which was the default level life on version 4.0 and considered a simple file but contains complete information about a level. Furthermore, a level is pass through a program called bsp that uses brushes in order to create the architecture of a level and places entities for the location of a level file. Then, it passes through Visible Information Set or VIS processor, then through the rad program.

a word of warning

Be careful not to rename the extension on .map files, or any other files. This will not change the file type. Only special conversion software can change a file from one file type to another.

what is a file extension?

A file extension is the set of three or four characters at the end of a filename; in this case, .map. File extensions tell you what type of file it is, and tell Windows what programs can open it. Windows often associates a default program to each file extension, so that when you double-click the file, the program launches automatically. When that program is no longer on your PC, you can sometimes get an error when you try to open the associated file.
