About .bk Files

BK files are backup copies created by FrameMaker software.
They use the MIME type application/vnd.framemaker, which links them to Adobe FrameMaker’s ecosystem.
These files are generated to safeguard your work by storing a previous version of a FrameMaker document. They help recover data if the original file becomes corrupted or is lost.

Based on information from FilExt.com, BK files play a critical role in ensuring data integrity and supporting efficient workflow recovery in technical publishing.

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 .bk file in the context of Adobe FrameMaker?

A .bk file is an automatic backup copy created by Adobe FrameMaker when you save a document. It contains the previous version of your work, ensuring you can recover data if the current file becomes corrupted or unwanted changes are saved.

How do I open a .bk file?

To open a .bk file, you typically need to rename the file extension back to the original format, such as changing .bk to .fm or .book. Once renamed, you can open the file normally using Adobe FrameMaker.

Can I convert a .bk file to PDF?

Yes, but you must first restore the file by opening it in Adobe FrameMaker. Once the backup is loaded (often after renaming it to .fm), you can use the Save As PDF function within the software to generate a PDF document.

Are all .bk files created by FrameMaker?

No, the .bk extension is a generic abbreviation for "backup" and is used by many different software applications. However, if the file is associated with the MIME type application/vnd.framemaker, it is specifically an Adobe FrameMaker document.

How do I disable .bk file creation in FrameMaker?

You can turn off automatic backups in the Preferences dialog within FrameMaker. Navigate to the Global or General settings and uncheck the "Automatic Backup on Save" option, though it is generally safer to leave this enabled.

Why does my computer not recognize the .bk extension?

Most operating systems do not have a default association for .bk files because they are intended to be backup copies rather than primary files. You may need to manually select Adobe FrameMaker from your list of programs to open it, or rename the extension.

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.
