Summary
OW Shredder is a free Windows application for erasing sensitive data from computers. It can erase individual files, folders, unused disk space, and entire volumes. The maker says it overwrites bytes and removes additional file-system traces; users can create a custom erase algorithm when the defaults do not suit a task. Alongside erasure, it includes tools for scanning and analyzing drive information and an autostart manager. Optional conveniences include a desktop widget, Windows context-menu integration, and automated recycle-bin cleaning. The help guide documents command-line use to unlock files and erase files or folders, including a hidden mode. The number of files that can be erased depends on available RAM. The maker describes the application as portable. Its help guide recommends full-drive encryption to reduce the risk of small restored fragments being used. The product page links to a help PDF and license, which users must accept to download.
