<html> <body> Hi, More fun for software archeologists.  I have quit a number of files with suffixes .pmd, .omi, and .uii.  Only .pmd is on a registered list, but of course my files have nothing to do with any of the definitions there.  That's because these are files in formats devised by the small company that I'm working for.  But if we do such things in a small way, there could be others doing such things in a large way. In this case it isn't so mysterious, because all of the files can be read in text format, and all are XML formats.  Can anyone find the dictionary?  Oh, and was that UTF8 or CP1252 (otherwise known as Windows-1252) character encoding?  And XML doesn't mean easy to read.  One of the developers admits that even he can't decypher some of the files with a .xml suffix.  That particular type of .xml file is just too complex.  Bob At 11:53 AM 11/27/2007, Ed Taft wrote: <blockquote type=cite class=cite cite="">Randall, In this connection, I have found the following resource useful: FILExt - The File Extension Source <a href="http://filext.com/">http://filext.com/</a> I am amused to note that it lists 9 definitions for PDF, only one of which is the Portable Document Format from Adobe.
