Deleting files and folders using standard Windows commands is not secure. east-tec InvisibleSecrets lets you selectively and permanently erase your confidential files and folders making them unrecoverable to any data recovery software. This is done with the help of the integrated File Shredder (DoD 5220.22-M compliant) which allows you to destroy any data beyond recovery, including shred the original files after creating a self-decrypting package. All shredding is based on advanced U.S. Department of Defense data destruction protocols and includes up to 4 unique shred methods.
