Opening R files

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

What is a R file?

Files that contain the .r file extension are most commonly associated with the Mac OS X operating system.

The R files that are used by the Mac OS system contain resource files that are referenced by applications which are run in the Mac OS X environment. These files store the shortcut functions and variable definitions for the associated software applications.

The RatFor Fortran software application has also been known to use the .r file suffix. These R files contain pre-processor source files that are created within the RatFor Fortran program.

The popular Pegasus Mail email application also uses the .r file extension. These R files contain resource files that are references by the email program.

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.
