Opening MK3D files

Did your computer fail to open a MK3D file? We explain what MK3D files are and recommend software that we know can open or convert your MK3D files.

What is a MK3D file?

Every day thousands of users submit information to us about which programs they use to open specific types of files.

While we do not yet have a description of the MK3D file format and what it is normally used for, we do know which programs are known to open these files. See the list of programs recommended by our users below.

We are constantly working on adding more file type descriptions to the site - the current count exceeds thousand by far, and more information about MK3D files will hopefully be added soon.

Try a universal file viewer

In addition to the products listed above, I would suggest that you try a universal file viewer like Free File Viewer. It can open over 200 different types of files - and very likely yours too! Download Free File Viewer.
