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.
Software that will open, convert or fix R files
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.
