NAME
7z - A file archiver with highest compression ratio
SYNOPSIS
7z [adeltux] [-] [SWITCH] <ARCHIVE_NAME> <ARGUMENTS>...
DESCRIPTION
7-Zip is a file archiver with the highest compression ratio. The
program supports 7z (that implements LZMA compression algorithm), LZMA2,
XZ, ZIP,
Zip64, CAB, RAR (if the non-free p7zip-rar package is
installed), ARJ, GZIP, BZIP2, TAR, CPIO, RPM, ISO, most filesystem
images and DEB formats.
Compression ratio in the new 7z format is 30-50% better than
ratio in ZIP format.
7z uses plugins to handle archives.
FUNCTION LETTERS
a Add
d Delete
e Extract
l List
t Test
u Update
x eXtract with full paths
SWITCHES
-ai[r[-|0]]{@listfile|!wildcard}
Include archives
-ax[r[-|0]]{@listfile|!wildcard}

Because my friends and I
use
DOS
WIN
Linux
until today
we sent
picture like
pic.zip
and save them in ZIP Files.
It is or it was much better
then
send pic.jpg.
