These are the file extensions used by the Holladay programs. Please keep in mind that file extensions, are clues to the operating system of the internal data structure in a file. Simply changing a file extension won't change the contents of a file. For example, if you have a word document called letter.doc, you can't rename it to letter.xls to change it to an excel document - doing so doesn't make any sense.
