About .cnt Files

CNT files are specialized files that serve different functions. They can contain plain text data for contour information or binary data for game archives.

Painter 3D Contour Data: These CNT files use the text/plain MIME type. They store contour or outline instructions in simple text. You can view or edit them with a basic text editor or design software that supports Painter 3D tools. Based on information from FilExt.com.
Hidden and Dangerous Game Data Archive: In this case, CNT files use the application/octet-stream MIME type. They hold binary data such as game assets or configuration details. These files work with the Hidden and Dangerous game engine and are not meant for casual editing.

CNT files are thus used according to their context. Use a text editor for plain text contour files and the game or its modding tools for binary archives.

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.

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.
