With File Shredder you can remove files from your hard drive without fear they could be recovered. Actually, the "delete" operation in Windows only removes bits of information from files so they appear deleted in OS. It is easy to retrieve those files using specialized file recovery software.
In order to remove, or shred files permanently from your system you have to use a program that is capable of rewriting the files with random series of binary data multiple times. This process is often called shredding. That way, the actuall content of the file has been overwriten and the posibilities to recover such a shredded file are mostly theoretical.
File Shredder has been developed as fast, safe and reliable tool to shredd company files. You can choose between 5 different shredding algorithms, each one gradually stronger than the previous one. It also has integrated Disk Wiper which uses shredding algorithm to wipe unused disk space. More on options of File Shredder check Online Help page.
