File type icon global association in Nautilus
I am running Nautilus 2.16.2 file browser in gnome 2.16.0 (RHEL 5.6 OS). I would like to associate a specific icon with every file that has the file type of .sas. I have found many references for associating an icon with a particular file, but I would like to apply this icon globally to all occurrences of any file that ends in .sas. How do I do this? More explicitly, there is a certain default icon associated with any .txt file that is created in the file browser. Where is this default icon located? Where is the file containing the command(s) that associate this default icon to any file ending in .txt? Thanks for any help.
