hello friends many times when we
download files or get files from
different sources we are unable to open
them because either the file format is
changed or it has unknown file format in
this video we will see how to find file
format or type of file here we have
three different files of different types
the first step is how to see file
extension open file explorer press out
and T to open the tool menu and click
folder options unselect hide extension
of known file types
[Music]
[Music]
now let us change the file format for
testing we change the first file type
from mp3 to zip format
[Music]
we then changed the second file type
from Exe to mp4
[Applause]
and at last we delete third file format
[Music]
now if we try to open these files they
will give us errors or will ask us for
the application to open
[Music]
now our task is to identify the correct
file formats of three files let's start
with the first file open website check
file type calm in your browser now we
upload our third file and click for
analysis
[Music]
results show that it is a jpg or jpg
file type
[Music]
if we change the extension of the file
to jpg then it will work correctly
[Music]
similarly we upload our second file
[Music]
the results show us that it is an
executable
it also runs correctly after changing
the file extension to Exe
[Music]
now we upload our first file and find
that it is MP 2 or mp3 file
[Music]
by correcting the extension it works
properly
[Music]
a file extension is used by windows to
identify which application will run it
if the extension is changed by mistake
or by purpose we can easily identify the
correct version this technique is also
very useful when we perform cyber
forensics and cybercrime investigations
I hope you understood how to find the
correct file please like share and
