7zip + jpg file = pretty compressed file
« on: May 20, 2007, 02:57 AM »
Do you like to compress files?
Do you like to hide important files from people?
Do you hate having a boring old plain compressed file?

If you answered yes to any of these questions, then this is the tutorial for you!
Ok, now that I am done acting like an infomercial, I will now show you how to turn a picture into an archive.
By archive I mean zip, rar, tar, 7z, and so on.
I haven't tried this on anything other that a jpg file, but I am almost possitive this would work with any picture, or any other file for that matter, like an mp3 maybe.
Anyways here goes.

1. Find a cool picture that you want to use as your new archive, and get 7zip (note that any other compression program that will let you right click on any file type and think that it is a suported archive, its kinda funny that 7zip does that)
2. compress any files that you want to, or just get an already compressed file, it doesn't matter what the extention is, or you can just get rid of the extention.
3. open the command prompt (start -> run -> cmd)
4. navigate to where your picture and archive file is (navigate in the command prompt)
5.type COPY /b picture name + archive name new picture name

You will then have a jpg file that when you right click on it with 7zip installed, you will be able to extract it.
this picture will be perfectly viewable, so you won't have to wory about people knowing that it is really a picture that has a bunch of porn in it.

~note for step 5~
picture name=the name of the picture you found
archive name=the name of the archive you made
new picture name=the name you will give to your new "picture archive"

your picture name is bunny.jpg
your archive name is files.zip
you would type in COPY /b bunny.jpg + files.zip bunny archive.jpg
that would turn my picture of a bunny into a zip file that contains what ever is in my files.zip archive named bunny archive.jpg

Have fun making pretty archives.
Update: I learned that you can also use exe files, like for instance if you have a program that is a single exe then you can put the program on your flash drive, and then archive config files for it inside of it.
You can also use txt files and html files, but I wouldn't because it adds a bunch of letters and numbers to the files, and so you basicaly loose the information that was in the txt/html file.

clever. someone should make a little gui tool for this.
sort of like poor-man's steganography.

I would make a gui for this, but I am not a programer, so the most I could possibly do is make an ahk script for it, but it probaly wouldn't turn out, so I will just have to use the command promt, unless someone else wants to make a gui (hint, hint)
