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 .omg file?
An .omg file is a proprietary audio format developed by Sony, utilizing the OpenMG copyright protection technology. These files typically contain audio encoded with the ATRAC3 or ATRAC Advanced Lossless codec and were used with older Sony Walkman devices and the SonicStage software.
How can I play .omg files on Windows?
Playing .omg files is difficult on modern systems because they often require the discontinued Sony SonicStage software. Most standard media players, such as VLC or Windows Media Player, cannot open them directly due to the proprietary OpenMG encryption.
How do I convert .omg files to MP3?
Direct conversion is often blocked by DRM (Digital Rights Management). The most reliable method is to use a legacy installation of SonicStage to burn the .omg files to an Audio CD, and then rip that CD back to a computer as MP3 or WAV files.
What is the MIME type for OMG files?
The specific MIME type associated with the high-quality ATRAC compression in these files is audio/atrac-advanced-lossless. You can find information on similar audio configurations in the /audio/ category on mime-type.com.
Why do I get an error trying to open old .omg files?
This usually happens because the file is protected by OpenMG DRM, which ties the file to the specific computer or installation where it was created. If you transfer the file to a new PC without the original encryption keys, the file becomes unreadable.
Is the .omg file format still in use?
No, the format is largely obsolete and has been superseded by universally compatible formats like MP3, AAC, and FLAC. Sony eventually discontinued the use of OpenMG and ATRAC in consumer devices in favor of these standard formats.
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.
