What are MRK files and how to open them

Are you having problems opening a MRK file or just wondering what they contain? We explain what these files are used for and show you software that we know can open or otherwise handle your files.

What is a MRK file?

Files that contain the .mrk file extension are used to save text files on digital cameras. These text files contain information that describes the order in which the pictures should be printed from the camera when the camera is hooked up directly to a digital photo printer. These files are also used by certain photo printing services.

The MRK file itself does not contain any image data, just the print order information. The MRK files can only be read by print services and printers that support the Print Order File format.

Files containing the .mrk file extension are also sometimes associated with the Pro/ENGINEER computer-aided drafting software. These files contain a Pro/ENGINEER Markup File that is used by the application.
