About .dec Files

DEC files are plain text files that store deck information for Magic: The Gathering.
They use the text/plain MIME type, meaning you can open and edit them with any basic text editor, such as Notepad.
These files are primarily used for managing and sharing card decks and may include details like card names and quantities.

According to FilExt.com, this format offers a straightforward way to work with deck data in digital card games.

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.

Is the .dec format compatible with mobile apps?

Many mobile deck-building apps for Android and iOS support importing text-based deck lists. If your app does not support the .dec extension directly, you can change the extension to .txt or copy the text content into the app's clipboard.

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.
