The power of C programming language, everyone knows!
You can make a program for any use C.

Here is a short example to make a program to create infinite number of folder in its current directory and also a program to overcome it -i.e- recursive deleter, which will delete everyting from its directory.

So, lets start making program that will create the infinite number of folder.
And now, a program which will remove these infinite folders in a second.

• I've created and compiled the programs to do so. Download the zip from github.
• Extract it to a directory.

• Now copy the run and exec folder to the place where you want to do experiment. Say 'Desktop'.
• NOTE: Copy run and exec both at Desktop.

• Run the vfolder using terminal or double clicking on it.
• As soon you run, it will keep creating infinite no of folder in run directory until you press ctrl+c or ctrl+z

Press CTRL+Z to stop the process or you will junk your pc.

• Now find the vremove file, and double click on it.
• It will clean everything in that run directory including itself.

Ya! You played well.
You have the code of this program in cpf directory.

Remember, don't use this script to junk any pc!
