About .met Files
MET files are binary documents used by older versions of OCR software.
They were primarily created by the OmniPage application to store scanned images and recognized text.
The MIME type application/octet-stream shows that these files are in a generic binary format, meaning they do not follow a standardized text structure.
- Legacy OCR processed documents: MET files contain data from scanned pages along with the output from Optical Character Recognition.
- Document archiving: They were used to store digital copies of physical documents.
- Software compatibility: Older versions of OmniPage or compatible OCR programs can open and edit these files.
If you encounter a MET file, consider using legacy OmniPage software or converting it to a modern 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.

FAQs
What is a .met file?
A .met file is a proprietary document format primarily created by older versions of OmniPage OCR (Optical Character Recognition) software. These files store both the original scanned image of a document and the text data recognized by the software.
How do I open a .met file on Windows?
To open a .met file, you typically need OmniPage software (previously owned by Nuance, now Kofax). Because this is a legacy format, modern versions of the software may treat it as an import file, or you may require an older version of the application to access it.
Can I convert a .met file to Microsoft Word or PDF?
Yes, but you usually need the original OmniPage application to perform the conversion accurately. Once the file is opened in OmniPage, you can generally export or 'Save As' to modern formats like .docx or .pdf.
Why can't I read a .met file in Notepad?
MET files are binary documents, often identified by the generic MIME type application/octet-stream. Unlike plain text files, they contain complex data structures for images and formatting that text editors like Notepad cannot interpret, resulting in unreadable garbled text.
Are there other file types that use the .met extension?
Yes, the .met extension is sometimes used for OS/2 Presentation Manager Metafiles, which are vector graphics similar to WMF files. If your file is not related to OCR or scanning, it may be a graphic file that requires a specialized image viewer or converter.
How do I fix a 'file not supported' error with a .met file?
This error usually indicates you do not have the correct software installed or the file format is obsolete. Try installing OmniPage Ultimate or a compatible viewer; if that fails, the file might be an OS/2 metafile or corrupted.
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.
