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 .cvr file?
A .cvr file is typically a QuickLink Fax Cover file used to store the layout and information for fax cover sheets. It contains binary data formatted specifically for QuickLink fax transmission systems.
How do I open a CVR file?
You need the original QuickLink Fax software or a compatible fax management utility to open and view these files properly. Because they are proprietary binary files, standard image viewers or word processors cannot open them.
Can I convert a CVR file to PDF?
You generally cannot convert a .cvr file directly to PDF without the original software. If you have the QuickLink application installed, you can open the file and use a virtual printer to "Print to PDF."
Why is the MIME type shown as application/octet-stream?
The MIME type application/octet-stream is a generic label for binary files. It indicates that the file contains data that requires a specific application to interpret, rather than being a standard text or image format.
Can I edit a CVR file using a text editor?
No, attempting to open a .cvr file in a text editor like Notepad will display unreadable characters. The file stores data in a binary format, which must be interpreted by the software that created it.
Are CVR files dangerous?
QuickLink Fax Cover files are data files and are generally safe; however, you should always be cautious with email attachments. Ensure your antivirus software scans any unknown file before you attempt to open it.
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.
