How do I ensure the files that I have deleted cannot be recovered?

Most of them still believe that once the files get deleted using a �Delete� button, Shift + Del button, emptying the recycle bin or formatting the hard drive, their deleted files are completely removed from PC. It';s not true. Though the files are deleted they can be easily recovered using an undelete software. Maintaining the privacy on storage devices is not as simple as we think.

Whether the file is deleted, Windows operating system does not delete that file permanently. Instead the allocation area or the index of the file system (FAT or NTFS) marks the area used by the deleted file as empty. But the actual raw contents of the file always exist even if the file has been deleted and waits for overwriting by the operating system. Deleted file, which is not overwritten, can be easily recovered. But, if you want to remove junk data from PC then have a look at

In order to ensure that your deleted files are erased forever, a file shredder should be used which permanently erases the files from the storage devices.

My file shredder tool allows user to shred folders from HDD in just a few steps.

The working principle of this software is, it will overwrite several times the area on the hard disk that was allocated to the files prior of shredding. The once shred data by this means is not recoverable by using any practical software or hardware methods. This software comes with an inbuilt scheduler, which can shred files periodically either at the start up of Windows or at the specified time and schedules the shredding tasks. During shredding, this software generates event log of complete shredding process. File shredder software comes with a context menu, which helps user to add files/folders to shredding zone.

File Shredder utility provides nine shredding methods and they are classified into different levels for erasing the data which are based on the security patterns

Low Security Shredding methods/ patterns

  • Fast Zero Overwrite
  • Random Overwrite
