Extension To Type

Last updated: 1995 Jan 22 Revision 3 Extension to Type Mappings There are many circumstances where files from alien (non-Mac) file systems are imported onto a Mac. Usually it is desirable to assign a Mac file "Type" and "Creator" code to such files, so that they can be operated upon, or merely viewed, by an appropriate Mac application. Unless you are prepared to inspect the contents of the file itself and deduce an appropriate Mac type/creator, the only evidence for the type of the file is the "filename extension" commonly used in DOS, OS/2, Unix and other systems. With certain Mac applications, automatic mapping of filename extensions to Mac type/creator codes can be achieved. A list of suggested mappings follows.
