The 
                  FILESUFFIX option specifies the file extension to be used for files that do not explicitly specify one. This option is switched on/off
                  according to file organization, by using the 
                  IDXNAMETYPE, 
                  SEQNAMETYPE, 
                  LSEQNAMETYPE, and 
                  RELNAMETYPE configuration options.
