About .efif Files
EFIF files are a vendor-specific image format. They use the MIME type application/vnd.picsel to signal their special handling in systems.
They are designed to store and display image data in environments that need efficient file transfer and display, especially in mobile or embedded systems.
- Main use: Storing image data for applications that require fast, efficient graphics handling.
- Usage cases: Often found in specialized mobile image viewers and other Picsel-related applications.
- MIME association: The application/vnd.picsel label helps operating systems and software recognize the format.
- Software support: Usually opened by dedicated applications such as the Picsel Viewer or similar vendor-specific tools.
Based on information from FilExt.com, EFIF files are best viewed or edited with apps designed to work with the Picsel file format.
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.
