Delete Files forever, free space from your Computer Hard Drive ensure secure sensitive data

 Almost all of us we delete  out dated or the  files not required in future from our computer hard drive
to free disk space. To delete a file from our computer,  we generally right click the file icon, click
delete(Or press delete Key on the key board). Now we receive a confirmation message  “Are you sure you want to send (File name) to the Recycle Bin” , and by clicking  “Yes’ it moves to the Windows Recycle Bin. When you empty the Recycle Bin  the file is permanently erased from the hard drive. But the real story is different. Neither the disk space is freed nor the  file das been removed completely. The file appears to have been trashed but a skilled technician may have no trouble restoring that deleted file using data recovery software – some of which are freely available online. Here’s
Whenever you delete  files or folders, the data is not initially removed from the hard drive.  the space
which was occupied by the data deleted is deallocated." and is available for use when new data is written to the disk. Until the space is overwritten, it is possible to recover the deleted data by using a low-level disk editor or data-recovery software.

To prevent your confidential files from getting into wrong hands, a permanently erase is necessary.
SDelete (Secure Delete) a free command line utility offered by Microsoft  is a real solution for it. This
utility overwrites all the free space prevents from any data recovery in future.

The SDelete is made available by “Technet”, a wholly owned subsidiary of Microsoft Corporation and you can download it free from here
