When you delete a file in a Windows operating environment, it is usually because you no longer need that file, do not want to keep it, or do not want anyone else to see it. If you think that by deleting the file, the data is gone, think again. What actually happens when you use the delete function is that Windows changes the first character of the file name. This lets the computer know that it can now use the space being occupied by that file. The problem is that, until the computer actually writes to that space (i.e. writes over the file), that deleted file can be easily recovered using any number of commercial and free software packages. Additionally, remnants of the data can be recovered from temporary files, swap files, and other Windows file system locations.

Shredder software from Infraworks solves this problem by immediately overwriting deleted files multiple times with different characters, vexing even the most sophisticated means of data recovery and making the data permanently unrecoverable. But what really makes Shredder unique is its ability to work in real time within Windows, capturing and shredding the host of temporary and backup files created by Windows or your software applications. Because Shredder works in the background, in real time, you don't need to remember to drag the file over to a special program for deletion like some other programs - when you delete using your program or Windows Explorer, Shredder automatically takes action.
