What it is

OW Shredder is a free Windows application for erasing sensitive data from computers. It can erase individual files, free disk space, and entire volumes. The maker says it overwrites bytes and clears additional file-system traces, and users can create a custom erase algorithm if the defaults do not meet their needs. Other included tools scan and analyze drive information, and an autostart manager is available. Integration options include a desktop widget, the Windows context menu, and automated recycle-bin cleaning. The help guide documents command-line use to unlock and erase files or folders, including a hidden mode. The maker describes the application as portable for individual users and companies. The number of files it can erase depends on available RAM, and the help guide recommends full-drive encryption to reduce the risk of small restored fragments being used. It is available as a free download; the product page links to a help PDF and license, which users must accept to download.
