Those are MySQL internals, not Koha.  Please ask a MySQL discussion
for further info, but the basic description is in
http://dev.mysql.com/doc/refman/5.1/en/myisam-storage-engine.html

   Each MyISAM table is stored on disk in three files. The files have
   names that begin with the table name and have an extension to
   indicate the file type. An .frm file stores the table format. The
   data file has an .MYD (MYData) extension. The index file has an
   .MYI (MYIndex) extension.

Hope that helps,
