WINDOWS File Shredder is a new feature in Malwarebytes Tools for Windows that securely deletes files from your hard drive or USB drive, making them completely unrecoverable even to specialized recovery software. It goes beyond ordinary deletion, which typically removes a reference to the file and may leave data on the drive that can be recovered with basic tools.
By permanently overwriting the file data, File Shredder prevents reconstruction or recovery, giving users real control over private information such as tax documents or contracts. The article notes the tool is particularly useful when cleaning up before selling or donating a device, or when removing files from a USB drive, and stresses there is no undo once a file is shredded. According to Malwarebytes Labs, the piece explaining File Shredder was published on 5 March 2026.
