What is MIME type "image/x-raw-minolta"?

A MIME type is a string that tells browsers and other tools how to handle a particular kind of file.

The MIME type image/x-raw-minolta designates a raw image file format used by Minolta cameras. It stores unprocessed sensor data for accurate, detailed image editing.

Files in this format keep the original data captured by the camera before any in-camera processing occurs. This allows specialized software to apply adjustments without losing quality.

Preserve full data for advanced post-processing
Allow non-destructive editing in raw converters
Ensure proper file handling for camera-specific workflows

Images of this type usually carry the MRW extension. Dedicated tools like RawTherapee or Adobe Camera Raw can decode and optimize these files.

The MIME type helps systems and applications identify the file structure and choose the right processing method. For more on file types, visit Filext.

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 are multiple MIME types listed for one extension?

Different applications and historical conventions may use alternative MIME identifiers for the same kind of file. Showing them all helps ensure compatibility across systems.
