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).
