The SITE command allows special FTP server command execution by supplying host-dependent parameters to the remote FTP Server.
For example, if your remote FTP server is an IBM i you might issue a NAMEFMT command to set the file location inside your remote session.
Setting NAMEFMT to 1 indicates to identify files in all IFS file locations, so all files and paths must be written in IFS notation (e.g. /home/dir).
Setting NAMEFMT to 0 indicates files are to be copied to and from the QSYS.LIB file system using a naming format library/file.member.
