How to create a Big size file ?

You can create a big size file using windows default command prompt itself.  Why we need huge size file? When you create virus  or you can use in your college for occupying the memory.

First of all Decide the Size of  huge file.  For eg, if you decide 1 milliion byte,then we should convert it to Hexadecimal format.  Use the Windows Calculator in Scientific mode to convert to Hexadecimal.

we are planned to create 1 million byte sized file.  So,Enter 1000000 in the calculator and click on the Hex option to convert it (1 million in hex is F4240.) Pad the result with zeroes at the left until the file size reaches eight digits 000F4240.

  • Now goto start->run
  • Enter "cmd" to open the window.
You may want to hide the admin or some other accounts for privacy purpose. If you are having public cafe or organization or school ,then you probably need.  I am going to guide you in this article to hide the Acccounts in Windows system.


  • Now go to start->run
  • Enter as "regedit" to open the registry window.
  • Navigate to this Path:
    HKEY_LOCAL_MACHINE\Software\Microsoft\WindowsNT\CurrentVersion\Winlogon\SpecialAccounts\UserList
  • In the Right pane, Right click -> New -> String Value
  • Right click on the new String Value and click Rename
Go to start->run
type as regedit
and hit enter
Registry edit will open.

Navigate to this Path by clicking the plus symbol:


HKEY_CLASSES_ROOT/CLSID/{645FF040-5081-101B-9F08-00AA002F954E}
You can see as Recycle bin in right panel.
Some files will be hidden from Users. If you want to see those files,you have to edit the registry. This hack will fit for both windows xp and Vista.

Go to Start-<run
Enter as Regedit
Navigate to

HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Explorer\Advanced
In the right panel ,you can see the superhidden registry
Right click on the SuperHidden
