How to prevent the recovery of deleted files

You must know that in order for a deleted file to be irrecoverable, a particular procedure is required which consists in overwriting the sector of free space on which it is located several times. To do this you can use CCleaner, a free tool that allows performance optimization, registry cleaning, privacy protection and secure deletion of data from your PC.

You can download CCleaner by connecting to the program's Internet page and clicking on the button Download free then press the green button Download. On the following page presses the link and download the file ccsetupxxx.exe. At the end of the download click on it twice and start the installation of the program on your PC.

At the end open CCleaner and connect the key to the USB port of the computer. Select in the software, the voice Instruments, from the left toolbar, and click on Drive remediation, in the menu that appears, and then check in Drive, your USB stick.

From the menu Quenching and tempering you can choose whether to overwrite only it free space or theentire drive. Define the number of overwrite passes from the menu Safety (the maximum is 35 steps) and click on Quenching and tempering, bottom right. At the end press the button OK.

By doing so you will have made your files on USB stick unrecoverable.

If you have Windows, valid alternatives to CCleaner are: Easer and EraserDrop, for Mac OS X I recommend Permanent Eraser.
