Data Destroyer 14.22t

Data Destroyer automatically and securely removes data content from hard drives or partitions in a manner than cannot be undone. You can erase files, folders, images, evidence of Internet activity and other sensitive data.

Data Destroyer is a program for permanently deleting files and folders. It can be used for secure deletion of all files on a disk (but it cannot be used to wipe an entire hard drive, including free space). To securely delete a file (on a disk or on any writeable magnetic medium such as a pen drive, a.k.a. a memory stick) means to delete the file by overwriting the data in the file many times (before removing it from the file system) so that the data which was in the file cannot be recovered by any means. Several overwrites (at least) are required for security, since just one may leave electronic traces of the original data which can be detected by very sensitive equipment designed to do this.

It is well-known that when Windows "deletes" a file it does not actually destroy the contents of the file but rather simply unlinks the file from the file directory system, leaving the contents of the file in the disk sectors. This data will remain there until the operating system re-uses those sectors when writing new data. Until the old data is overwritten (and this may take months or longer) it can be recovered by programs that read disk sectors directly, such as forensic software (so called because it is used to obtain evidence in criminal investigations and also in legal discovery). If you wish to make sure that information in files containing confidential information (such as financial data, company plans, proposals, etc.) can never be recovered after deletion then you need a program such as this.
