The file considered for reference is then taken right from the directory area still by means of overwriting. The file may be written over thrice, even in cases when it is extremely sensitive. In essence, a file shredder does the trick of overwriting the file. With the usage of specially designed equipment, the data can still be retrieved by any avid computer user. Even if the data is already overwritten, there is still information that remains underneath the surface layer can. This actually works once the data concerned has other files overwriting it, which may not occur for a longer time period.
#Computer file shredder software how to#
One who knows how to look into computer files could very well detect the location of the data on the hard disk and recover it quite easily.
Yet the point remains that the files are still there and it is still retrievable. The only difference is that the file no longer comes with its original name making the process of retrieving it very difficult to do.
There are so many people who think that the deletion of a file and emptying it right into the recycle bin means that it is already gone for good - it is still actually contained in the hard disk.
Not only does it dispose of the file, it also eliminates even the most secure file shredder software, in which anything that has reference to the shredded file is also wiped out in its history and directory securely and permanently. A file shredder was developed to perform similar functions as that of a paper file shredder.
