  1. Locking a computer using an USB drive can be done using a software “folder security 1.0.2”. With this software we can lock and unlock our computer with USB drives and also we can block and unblock USB ports and we can prevent data copying. This works perfect and a very best software.

  2. IS this fully secured.I mean will I be able disable this security without the device???

    1. Yes of-course this security can be disabled without the device in-case if the device is lost or broken……!

      This could be done by clicking “I Lost My Pendrive” button at the bottom left corner of the screen,
      this will promote you to enter the master password of the software. Once the computer is unlocked you will find a window with the options for disabling and changing the device.
