An advanced and feature-rich application for securely deleting files and even entire drives.
Notable is the inclusion of a partial implementation of the NTFS file system, used to remove all traces of the files.

Main functionality written in C++, extended by a library written in C# with features like file filtering, scheduling and plug-ins, and a software interface build using WinForms available as a stand-alone application, Windows Shell extension and as a Microsoft Management Console plug-in

• Wiping of files, folders and free space on a disk.
• Wiping of cluster tips, Alternate Data Streams and MFT file entries (under the NTFS file system).
• Built-in and user-defined wipe methods supporting patterns, random data and write verification.
• Secure random number generators (ISAAC and Mersenne Twister) and seed generator.
• Parallel wiping for targets found on separate physical disks.
• Scheduling of wiping tasks with custom options and before/after actions.
• Plug-in framework allows extending the existing functionality.
• Actions that can be executed at the beginning/end of the wiping process.
• PowerShell scripts can be used to controll the wiping process or scheduled tasks.
• Windows Shell integration (context menu entries in Windows Explorer, Open/Save dialogs, etc.)
• Microsoft Management Console integration.
• Rich reporting, logging, debugging and crash protection capabilities.
• Exporting and importing of options, wipe methods and scheduled tasks.
