procedure RegisterFTPListParser(
    const AParser: TIdFTPListParseClass
);

RegisterFTPListParser is a procedure used to add a TIdFTPListParserBase descendant to the list of parser classes available for use in the Indy FTP client. 

RegisterFTPListParser uses the Add method in GParserList to store the object reference in AParser in the list of registered parser classes. 

By default, both TIdFTPLPNList and TIdFTPLPMList classes are registered for use in the Indy FTP client. These represent the parsers used for listings in the NLST and MLST formats. 

Use UnregisterFTPListParser to remove a registed list parser class from thelist available for use in the Indy FTP client.
