Wipe PC features are very important to have in your system. This is because the mere act of deleting files from your system does not really achieve the results that you want to achieve. If you think deleting a file from your folder means that it has been completely erased from your computer, then you are in for a startling surprise. The file still exists, even after you choose the option to delete it. You no longer see the file in your folder, but the space that has been assigned to it upon its creation still exists. If, by some unfortunate chance, a hacker somehow infiltrates your system, and that deleted file catches his attention, he can bring that file back into existence just from that assigned memory. Thus, it is very necessary to have wipe PC features in your system. This way, basic recovery programs would find the retrieval of deleted files difficult to do.



But why is this so? Why then is there a need to have a delete option in your computer, when the file is not completely deleted in the first place? You have to bear in mind that all files existing in your computer do take up space in your system's memory. The existence of too many files can make your system crawling quite painfully, especially if your memory is not too big to begin with. Thus, it would still be very important for you to delete unnecessary files as you move along. The file is indeed deleted, you know. It is just the memory assigned to it that remains in existence. And it will remain in existence until such time that another file created will be overwritten on that free space. Good for you if no hacker is able to infiltrate your system because all you have to do is wait for such time that the space will be overwritten by another file. Still, this can very well be a long wait for you.

When you delete a file, you actually just move it to the recycle bin of your system. The file can indeed be physically seen in the recycle bin. However, the file's directory entry, which includes the filename and its complete path, is transferred into a particular hidden folder. Once this happens, the file is renamed accordingly. The original filename is then transformed into what is known as a hidden index file, which is termed as INFO2. Have you noticed the Restore File option in your recycle bin? Clicking this option would actually move the deleted file back into its original location, right? This is because that assigned memory has not been overwritten yet. Retrieval of the deleted file, which has just been moved into the recycle bin, is then possible.

But who's to say that the same would not happen if you empty out the contents of your recycle bin, right? For there are indeed a lot of refined computer programs that have been specially designed to retrieve deleted files just from the assigned spaces that they used to occupy. Thus, it would really help to have wipe PC features, so that you can efficiently wipe whatever free space in your system, without having to wait for these spaces to be overwritten.
