The file in the zip is an AS/400 save file. I like to do it like this:
-Unzip the file into a directory on the PC
-start a DOS prompt in that directory
-start a FTP session to your 400
-then log into the ftp server
-from the ftp > prompt
ftp > cd qgpl
ftp > bin
ftp > quote site namefmt 1
ftp > put savefilename.savf
ftp > quit

then from the 400 command line
rstobj *all qtemp *Savf

As an alternative way to upload the save files on this page
I like to use the Install Aid program from Bug Busters Software Engineering.
