Hello and welcome back.
I'm now going to give you an exercise going in this sample that from the resource section and put it
on your desktop inside here, you will find some sample samples for you to identify the five form it
is is executable file is a text file using a picture file, is it Cifas or whatever.
So use it to find out.
And the way you do that is you simply dry the file into tonight and tonight we scan for you and you
give a result here to tell you how many percent match for the various results.
So as you can see here for sample three one one, it is an executable.
How about a second one?
Second one is a Zimpher, so we know that this is if we can actually rename this to become a Zimpher,
right, you can copy and paste here and.
What is the city behind and then we can extract it?
And there you go.
It is as if you can see content.
One.
It is a pig farm and it is a picture, so it is a picture file you can copy here and he's a pig.
So we put Yang fire tension and open it with a picture of you.
For example, photo were.
And there it is, picture.
So I live the rest of the exercise for you to try on your own.
There's something else I want to show you.
There's also a common language treatment.
It is seen in the C program where you put on man, I told you today he is over here three.
So this is doing the same thing as the new guy version, so let me show you how to do to use it.
You can open the command from clicking on the Windows icon search for ACMD and click on it.
Now you open the common front pages to the Tazawa, crackling and pinching pennies, programming the
taskbar so that you can have easy access to it in future and then you never get to this location.
So let's copy this part here and taxied space to base it here in presidenta.
And now you are in this location.
OK, so if you wanted to scan the sample, the sample on a desktop, you need to get it back to copy
the path and get over here, run the commentary EIC spacebar and pace the path to this location on the
desktop, put in space and then type the name of the sample presenter and tell you what is the same
result.
But it is graphical.
It is in command line form rather than the graphical user interface.
So if you were to scan a sample number three to history, you should get the same result.
It is A, B and C, so this is the online version of this, if you wanted to make this command available
anywhere else in your file system, then you need to add the path to environmental variables.
So how do you adjust to the environment or both?
You just click here and search for and the environment and environmental variables.
And in the system, environment are worsening over here, look for the environment they're both putting
in and the system for the party, but this one.
So even to add in spa, so click on edit and into the back of this path, don't do anything.
Just write a semicolon.
And at the path to this program, to this for the seizure of a tree.
So C zero five three to sign this.
So we just copy this and then a penny to the back to the back here and piece that so nicely.
OK, so now your Windows knows where to look for this program.
So let's say I close this.
After you have changed your environment variables, you need to close the command from reopening again
so that you can read the new environment variables.
So no, no matter where you are, you don't have to go to the leaseholder in order to use it.
You can just fire away from wherever you hide and just treat the orangy and he should be able to run
it.
So this is how you act.
A new path to your environment are so in future, if you don't any kind of command line program and
you wanted to test to see from anywhere in your file system, remember to head the path to your binary
to executable, add it to your environment variable using the technique I have just demonstrated.
So I leave you now to complete the rest of the exercise using the both either one of these two here
to familiarize yourself with the how to identify file formats.
That's all for this exercise is your lecture.
Thank you for watching.
I'll see you in the next one.
