NAME

       regfiletype - Identify the formats of Regina data files

SYNOPSIS

       regfiletype file ...

DESCRIPTION

       This  utility  determines  which file format a given Regina data file is in.  You may pass
       multiple files on the command line; the format of each file will be  written  to  standard
       output.

       Only   Regina's  modern  XML-based  file  formats  are  recognised  (both  compressed  and
       uncompressed).  In its very early years, Regina  used  an  impenetrable  and  undocumented
       binary  format;  this  was  replaced  with  XML in 2002 (Regina 3.0), and support for this
       format was removed completely in 2013 (Regina 4.94).   If  you  still  need  to  recognise
       and/or read files in this ancient binary format, you will need to download Regina 4.93.

MACOS USERS

       If  you  downloaded a drag-and-drop app bundle, this utility is shipped inside it.  If you
       dragged   Regina   to   the   main   Applications   folder,   you   can    run    it    as
       /Applications/Regina.app/Contents/MacOS/regfiletype.

WINDOWS USERS

       The  command-line  utilities  are  installed  beneath the Program Files directory; on some
       machines this directory is called Program Files (x86).  You  can  start  this  utility  by
       running c:\Program Files\Regina\Regina 7.0\bin\regfiletype.exe.
