From the developer: "How secure is your trash? You shred your confidential paper documents, but are you as careful when disposing of confidential electronic documents from your computer? You need ShredIt, the eDocument shredder. Throwing a file in the recycle bin does not remove the file contents from the hard disk - it just removes the file name from the directory, leaving the data intact and vulnerable. What you threw away can be recovered by anyone with access to your computer - your roommate, a business associate, the thief who just emptied out your office. Don't risk throwing private and confidential data in the recycle bin - securely delete it with ShredIt.
"ShredIt for Windows provides an easy, permanent way to securely delete files, folders and disk free space. ShredIt is an easy to use 'drag and drop' application, like the recycle bin - just drag the item onto the ShredIt icon and let ShredIt do the rest. The 'confirm before shredding' feature allows you to require confirmation before shredding to give you the opportunity to cancel before you've shredded an item. This is important since the item is not recoverable once it has been shredded. Key features include: an easy to use 'drag and drop' interface, the option to shred shred files, folders, disk free space; the 'Confirm before shred' feature, a configurable overwrite pattern and number of overwrites."
