About .exmp Files

EXMP files are used in SimCity 4 to store game data in two distinct formats.

Text Format: These files use the MIME type text/plain and are known as SimCity 4 Cohort. They can be opened with simple text editors like Notepad or Notepad++.
Binary Format: These files use the MIME type application/octet-stream and are referred to as SimCity 4 Exemplar. They are intended for more efficient data processing by the game and usually require specialized tools or the game itself to interpret.

EXMP files often contain configuration details, simulation parameters, or asset data critical for game functionality.
Based on information from FilExt.com, the choice between text and binary formats reflects a balance between ease of editing and optimized performance.

Relationship between file extension and MIME type

A file extension is a suffix at the end of a filename that indicates what type of file it is. File extensions help both users and operating systems identify what application should be used to open the file.

File extensions are typically separated from the filename by a period (dot) and consist of 2-4 characters, though they can be longer. For example, in the filename "document.pdf", ".pdf" is the file extension.

File extensions are closely related to MIME types, as they both serve to identify the format of a file. However, while MIME types are used primarily by web browsers and servers, file extensions are used by operating systems and applications.

FAQs

What is an .exmp file?

An .exmp file is a data file used by the video game SimCity 4. It contains definitions for game objects, known as "Exemplars" or "Cohorts," which dictate how buildings, vehicles, and props behave within the simulation.

How do I open an .exmp file?

The method depends on the file's internal format. If it is a text-based Cohort file, you can view it with any text editor like Notepad or Notepad++. If it is a binary Exemplar file, you must use specialized modding tools like iLive Reader or SC4Tool.

Why does the file look like random symbols in Notepad?

You are likely trying to open a binary .exmp file in a text editor. These files typically correspond to the MIME type application/octet-stream and contain compiled data that standard text editors cannot decode into human-readable text.

Can I convert .exmp files to other formats?

Generally, no; these files are specific to the SimCity 4 engine. However, advanced users with modding tools can sometimes export the data to XML or convert between the binary and text representations for easier editing.

What is the difference between Text and Binary .exmp files?

Text format files are often used for "Cohorts" (parent definitions) and use the standard text/plain MIME type. Binary files are usually "Exemplars" (specific instances) optimized for game performance and are not meant to be human-readable without a decoder.

Is it safe to delete .exmp files?

If the file is located in your SimCity 4 Plugins folder, deleting it will remove the associated custom content or mod from your game. Deleting core game files will likely cause the game to crash or malfunction.

General FAQ

What is a MIME type?

A MIME (Multipurpose Internet Mail Extensions) type is a standard that indicates the nature and format of a document, file, or assortment of bytes. MIME types are defined and standardized in IETF's RFC 6838.

MIME types are important because they help browsers and servers understand how to process a file. When a browser receives a file from a server, it uses the MIME type to determine how to display or handle the content, whether it's an image to display, a PDF to open in a viewer, or a video to play.

MIME types consist of a type and a subtype, separated by a slash (e.g., text/html, image/jpeg, application/pdf). Some MIME types also include optional parameters.

How do I find the MIME type for a file?

You can check the file extension or use a file identification tool such as file --mime-type on the command line. Many programming languages also provide libraries to detect MIME types.

Why can one extension have multiple MIME types?

Different programs and historical usage may assign various MIME identifiers to the same file format. Listing them together helps maintain compatibility across tools.
