hello and welcome in this video I will
show you how to download install and use
7-zip on Windows
I will also briefly explain what 7-zip
is and what I can do okay so the first
step is to open up your favorite browser
and navigate your favorite search engine
and then search for 7-zip now the link
we want is the home page which I'm
showing you here so simply click on the
link and by default on the home page you
were presented with the latest stable
version of 7-zip which at the time of
making this video is 7 sep 18 point 0 1
okay
so briefly what is 7-zip 7-zip is free
open source software basically it's a
program that allows you to archive files
and folders ok it's really nice it's a
very powerful stable and excellent piece
of software ok it uses a 7-zip format
which we don't have to get bogged down
the lzma compression crucially it allows
you to unpack virtually every archive
format you can think of I've just
highlighted them there that includes all
the common archive file formats as well
as for example ISO files which are
images of disks and CDs and DVDs and so
forth also you can create archives of
the 7-zip format as well as the common
zip format and the tar format and gzip
that's use on UNIX systems and Mac OS X
systems it also supports encryption and
I will show you how to encrypt and
decrypt files securely in my next video
ok so we want to download the latest
version we're given a choice of either
32-bit or 64-bit you should download the
version that corresponds with the
version of the Windows operating system
that you are running right now if it's a
32-bit or 64-bit I have a video that
I've already made on a shows you how to
determine whether you're running 32-bit
or 64-bit I'll hopefully put up a link
in this video you can click on that
to view it if you need to find out what
version you're running right now so I'm
running in 64-bit version so I'm gonna
download the 64-bit XE so when I click
download and it's gonna prompt me and
with the file name save this file I'm
gonna say it's click save file perfect
so it's downloaded out to my downloads
folder so I'm going to open up my
windows explorer and there it is in my
downloads folder perfect the next step
is to simply install 7-zip and to do
that we simply double-click on the XE
file so I'm gonna double click and then
I'm given an alert to say do you want to
allow this app from an unknown publisher
to make changes on your device and you
select yes
so I'm now been prompted with a setup
dialog box the destination folder I
would recommend you choose the default
destination folder as it happens I
myself install my software into a folder
called software so I'm going to do that
now but I recommend you accept the
default installation and parameters and
then click install and then click close
great that's it installed so to use
7-zip it's actually really easy by
default when you install 7-zip it is
integrated with the Windows Explorer
such that if I want to archive or 7-zip
a folder I simply have all I have to do
is select a folder and then right-click
over using Windows Explorer and there
will be a menu option available to me
you'll see 7-zip there and within that
we can select several options at the
archive compress an email the tests
folder than 7-zip and so on the easiest
the most common options you will Lou you
will use I suspect will be add to test
folder that 7-zip or add to test folder
dot zip so that zip I suppose is the
most compatible so we'll select that so
it will simply archive the folder into a
dot zip file great so to demonstrate how
to unzip it I just want to delete the
test folder so now to demonstrate on zip
it it's something very similar you
simply right click over the file select
7-zip and then you can choose extract
here
so by extracting here it will extract
the contents of the archive file and
given that the archive was consists of
actually a folder it will extract a
folder and that's an important point and
let me demonstrate so I go into my test
folder as you can see I've got one file
and a test subfolder so I can select
both of those and say right click 7-zip
and add to test folder that zip and it
creates the archive as we expect it now
if I delete the file in the folder and I
now unzip it is in the same manner 7-zip
extract here it will actually create the
file and the folder in the current
working folder so it's actually a nice
feature so if you act the way you
archive it is the way it will be
extracted by default that's a really
nice feature last but not least I want
to show you some of the options that are
available with 7-zip so let me go out I
think they'll eat that just for a moment
go back out and and as I leave my zip
file here so I can actually again select
the folder right click select 7-zip and
choose add to archive and this is the
option that gives me I suppose the
facility to configure how I'm on my
archive to be am constructed so here we
can specify the name you can choose any
custom name we like we can choose the
archive format there are four different
formats and 7-zip and zip being the most
common we can choose compression level
the Ultra which is really high
compression but very slow to store or
fastest which is very fast and but low
compression there's the different
compression methods I'm not going to go
into them these are relations these
options here are dictionary size word
size and solid block size are related to
the am the compression method that we
use the number of treads this is
excellent a 7-zip is more fully
multi-threaded which means it will make
use of all cores and the data are
installed and you're a physical computer
and the memory available you can choose
to split volumes which means you can
create an archive and have a consists of
multiple files if
example you wanted to back up your
archives onto a CD for example and your
archive your files were like 2 gigabytes
you could split them into files of 650
megabytes as indicated here so it's a
really nice feature and then specialist
parameters for those who are experts in
using 7-zip and you can update mode out
and replace and so forth update and add
synchronize and so forth you can create
self-extracting archives which means you
can actually create an archive and then
give it to someone and in order for them
to own archive it they simply double
click they don't need 7-zip installed
itself and an compressor and so on I
will actually do a video on how to
encrypt because it's a little bit and
peculiar and I want to explain how it
works and I don't want to make this
video too long so what I explain that in
my next video so that's really it um I
suppose one more feature although this
is for Windows I want to show you that
if ever you want to actually take your
archive and use it on a Mac OS X
operating system which I do commonly I
share files between my Windows PC I'm a
Mac OS laptop um you can actually use it
and archive it and extract it using a
file a program should I say called KEK a
on Mac OS so there it is kek a the mac
OS file archiver and the beauty about
this archiver is it will extract 7-zip
precisely because it actually its main
compression core is p 7-zip which is a
seven support so if you like this is the
Mac OS X equivalent okay that's all I
wish to say thank you very much I hope
you liked the video in my next video I
will actually go to in detail how to
properly encrypt using 7-zip
