ZIP - Compress files so that they take less space and save transmission time.
ZIP can store multiple files as one and transfer them together,
and it is fully compatible with PKWare's PKZIP versions through 2.04g.
ZIP also supports long filenames, for transport to operating systems
such as Windows XP/NT/2000/ME, Windows 95/98, OS/2, PRIMOS, etc.
You can even create PC compatible self extracting executables on UNIX.
And now ZIP can read and create ZIP files encrypted using the
128 bit or 256 bit AES encryption.
