Germany
What it is
OW Shredder is a free Windows application for erasing sensitive data from computers. It can erase individual files, clear free disk space, and wipe entire volumes. The maker says it overwrites bytes and removes additional file-system traces; users can create a custom erase algorithm if the defaults do not meet their needs. The application also includes tools to scan and analyze drive information, plus an autostart manager. A desktop widget, Windows context-menu integration, and automated recycle-bin cleaning provide additional ways to use it. Its help guide documents command-line operations for unlocking and erasing files or folders, including a hidden mode. The number of files that can be erased depends on available RAM. The maker describes OW Shredder as portable. The help guide recommends full-drive encryption to reduce the chance that small restored fragments could be used. The product page links to a help PDF and license, and users must accept the license to download. The license provides the software as is without warranties.
