Nowadays, computers seem to be everywhere. They have truly revolutionized almost every aspect of modern society, by performing certain tasks much faster and much more efficiently. Because of their great effectiveness and inherent versatility, computers have been adapted for use almost everywhere conceivable. Offices, schools, and homes have all found their own uses for computers.

As computers become more and more commonplace, digital storage of data also becomes more and more the norm. Digital data is what computers can understand and use, and can be stored in a variety of media, such as a computer’s built-in hard disk drive, or removable devices such as CDs and flash drives. Digitizing data has the benefit of making it much easier to work with, organize, and disseminate, using computers.

With this new type of data storage also come issues about keeping data secure. In response, some programs have implemented the possibility of protecting files and directories with passwords.

On the other hand, when files or data are deleted, sometimes it may be the case that their contents are not supposed to be recovered. This is actually not the case when ordinary file deletion is performed! When a file is deleted, it does disappear from its directories, and appears to have vanished completely, as desired. However, it is actually not overwritten on the hard disk itself, and the data remains on the disk, available to be recovered by prying eyes.

In fact, there exist utilities to do just that: recover deleted data, thought to be lost. While this may be a good capability to have, sometimes data just needs to vanish, without any trace. For instance, when selling or transferring a computer, deleting any and all personal or confidential information might become necessary.

Physically destroying the hard disk drive or otherwise rendering it unusable is of course an option, but is not always practical. This is especially true when only a particular file needs to be deleted, and not the entire hard disk.

This is where the use of a file shredder comes in. A file shredder is a program that, as its name implies, is able to permanently delete (or “shred”) a file, directory, or collection of files and directories. This is done by actually overwriting the data on the surface of the hard disk, thus removing the traces of the file that may have been used to recover its contents. Some file shredders perform this overwriting process several times to ensure that, indeed, nothing of the previous information remains.

The data on the disk corresponding to the file or files to be shredded are overwritten with randomly generated data, to mask it. Data recovery after a file has been shredded is still possible, in theory, but in practice it becomes very difficult. Thus the use of a file shredder represents an adequate security measure for most applications.

There are both free and paid file shredders available, with varying degrees of sophistication and user-friendliness. With the many choices on the market, there is sure to be a file shredder program appropriate to any particular situation and required level of security.

A computer file shredder was created for the same purpose as the paper file shredder. The intent is to complete obliterate not only the file, but in the most secure file shredder software, any reference to the file that was shredded is also shredded in the history and in the directory. Many people do not realize that a computer file that is deleted doesn’t go away, it still resides on the hard drive or disc–it just doesn’t have a name any more, so there is no easy way to access it.

Someone who knows how to search computer files can fairly easily determine where the data is on the drive and recover the information. This works until the data is written over with other files, which may not happen for a long time. Even if the information is over written once, in many cases, the information underneath the top layer can be accessed, using sophisticated equipment.

In essence, what a file shredder does is to overwrite the file. If the material is extremely sensitive, the file may be overwritten 3 times. Then the reference to the file is removed from the directory area, using the same means–overwriting.

If defragmentation is used on the areas in the drive where sensitive information was stored, this will mean that it’s even more difficult to use a file shredder and be certain that the information is truly unrecoverable.

Any time sensitive business or personal information is stored in a computer file, there is always the need to use a file shredder if the computer is sold or donated. A recent study found that a large proportion of donated used computers contain personal information and files on the computer, even when the files have been deleted.

Shredding, also known as file wiping is commonly used for reasons of confidentiality. Copyright and trade item piracy is a serious business. Trade espionage relies on being able to steal secrets about the business of a competitor in order to profit from such information. File shredding or file wiping is just one part of the entire security program. Prevention of theft of sensitive documents and electronic files helps stop computer file theft. Making sure sensitive information is stored in encrypted files and maintaining the security of the encryption key is another important file security effort.

If you want to be absolutely positive sensitive information can never be recovered, methods such as destroying the data with acid, or by incinerating the disc. Another method is known as degaussing which is a methods of decreasing or eliminating an unwanted magnet field. This is accomplished by the use of an electromagnetic coil and was used as a method of protecting military ships against magnetic mines.

In most instances a triple overwriting in order to shred information in a file is overkill for the home computer owner. Overwriting a large file, such as one of 100MB or larger can take an tremendous amount of time, and is not warranted in most cases for the small business person, or individual for home security.
