LINKSWT  FILE is  defined in  CONTROL FILELIST  which is  peered with  all the
backbone servers. Therefore, when  you do a PUT of any  file on this filelist,
it gets distributed to all the backbone servers. This is the "normal" case for
a PUT  command, ie you want  to update all  the servers which are  supposed to
have the file. If  you want to update only one server,  use the NODIST option,
ie:
 
           PUT LINKSWT FILE CONTROL NODIST PW=xxxxxx
 
I  think what  mislead you  is you  wanted  to have  the file  stored on  your
LISTSERV's A-disk as per a PUTC command (which is never distributed and causes
the file to be stored 'as is' on whatever disk you selected).
