It even simplifies the process of deletion by automating the cleaning process with batch files and shortcuts. You can also use a scheduler to time the cleaning process. It works by overwriting sensitive data with carefully selected patterns. You can support files, folders and subfolders deletions at times. Your confidential information remains confidential as this tool leaves no trails of deleted information. It allows you to right-click on the item to be shredded from the Windows Explorer or recycle bin files and select for deletion.
    Completely protect the security of data deleted from the system.
