WinZip is very useful software to compress files and combine many files to a single password protected file and also if you want to copy a single large file which not fit in the floppy disk you can use winzip to compress it and copy it in more than one floppy disk, nowadays nobody is using winzip because of large capacity flash memory and cd writers but in old days when there was not flash memory and cd writers most of the peoples were using winzip as compression and copying tool, I am using it since 1993 when the name was PKZip in MS Dos.
