Opening OPK files
Did your computer fail to open an OPK file? We explain what OPK files are and recommend software that we know can open or convert your OPK files.
What is an OPK file?
While we do not yet have a description of the OPK 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 OPK files will hopefully be added soon.
