File Extensions

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.
