now you might have heard of compressing
files in zip or rar format but you can
actually achieve more compression by
using the 7z format here is a quick
comparison of a file I try to compress
in different compression formats the
original size of the file was 344
kilobytes using the zip compression
format I was able to achieve as a
compressed size of 308 kilobytes with
rar it was at 307 kilobytes while with
7-zip it was the lowest at 305 kilobytes
if you want to open 7-zip format files
or you want to compress files using the
7-zip compression you'll need to install
an app which will let you do that
the one I recommend is called Zee
archiver and it's available for free on
the Google Play Store and here is how
you can compress files using the
archiver you open the app and locate
whichever folder the file is in so mine
was already in downloads I'm gonna go
back and then I'll just have to tap on
the file and then you get this menu and
I'm gonna select compress here this will
give me a variety of options the first
fill here refers to what you want your
compressed file to be called and I'm
gonna keep it same here
however if you want you can always
change it the second field is the
archive format and you need to make sure
that you have set it to 7z if you want
it to be compressed in the 7-zip format
and you can always change the
compression level if you have really
large files you can go with ultra
however it will take a little bit more
time for it to compress or uncompressed
that file you can choose how you want
your encryption to be done as well so
right now it's set to data however you
can always opt for data and filenames to
be encrypted and then you can set a
password as well if you want
once you're done setting that up just
select ok how do you have your
compressed
file in 7-zip format if you want to open
a compressed file all you have to do is
just tap on the file and you'll get the
menu where you need to select view if
you want to view the contents of the
file you can always tap on it once more
which will let you open the file or you
have the option to extract the file as
well I'm going to demonstrate to you how
to open the file and then it will give
you the option to select whichever
software you want to open it with so
let's try the drive PDF viewer and see
if it works and I have the PDF file now
opened directly from the 7-zip archive
file now going back if I want to let's
say extract the file I just have to tap
again and instead of viewing I can do
extract here I can do extract to the
archive folder or I can extract to a
different location as well if you want
to test you can always test the
integrity by just selecting it and it
says archive does not contain any errors
I hope you find this video useful if you
have any kind of questions sorry if you
have any other compression utility that
works better do let me know through
comments thank you for watching this
