If you are going to sell your PC There is a need to wipe off important and personal files from your computer especially if you are disposing the old personal computers in favor of brand new ones. Second-hand users of your soon-to-be-disposed computers might be able to install recovery software and retrieve your personal and confidential files without you knowing it. Worse, such files might be improperly or maliciously used. During the current computer age, there is a need to protect yourself and your company from any potential problem that may arise from such an occurrence. Thus, there is a need to invest in a file shredder program. A better file shredder Apart from this overwriting, these file shredders also remove the markers on the file, unlinking it from whatever directory it used to be in, leaving it truly untraceable. Some file shredders go even further, and try to ensure that any metadata (that is, information about the data itself) that may remain in the file system is also erased. It should be noted that file shredding is much different from “deleting” (as mentioned before) or even “formatting”. These processes do not erase the file information as thoroughly as a file shredding utility would. Under normal conditions, these operations from within the native OS (or operating system) may be enough, but again if security is a consideration, using a file shredder would be better. Many software options are available to those in need of a file shredder. There are free programs as well as commercial ones, with varying degrees of functionality and usability. In general, free programs can get the basics done well enough, but for more sophisticated options commercial ones perform better. File shredder - how does it work Information security becomes even more important for bigger organizations that organize and access their vital information on computers. When reorganizing computers or disposing of old computers (to acquire new ones, for instance), shredding the hard disks is an effective way of making sure that private data is not accessible. File shredders work by actually overwriting the file’s location on the disk. That is, these shredders randomly change the values of the bits on the disk that make up the file. Some file shredders even repeat this process more than once, but for modern drives it has been found that, generally, one overwriting is enough. By overwriting the actual disk space that the file used to occupy, its traces are removed, and it can no longer be reconstructed as easily. (In fact, it becomes practically impossible.) Use file shredder or keep files in Recycle Bin? While it may be handy to be able to undo accidental deletions, this fact also opens some security liabilities. Confidential information thought to be deleted and beyond recovery already may in actuality be recovered and put to malicious use. When a computer changes hands (simple transfer or perhaps a purchase), the information of the previous owner, if not shredded, may be recovered and used for such things as identity theft. Delete file command in your computer The deletion of files from a computer may seem permanent and irreversible at first glance, but in actuality this is not the case. It is often too resource-intensive to set every single bit of a file to 0 (that is, completely clear it and remove all traces) when deleting it. Most operating systems, when performing the ‘delete’ command on a file, do not actually eradicate all traces of said file. Instead, what actually happens is that the disk space that the deleted file used to occupy is now marked as available for use, and the file is indicated to be gone from its directory. However, the actual contents of the file are not removed from the disk. This is what allows the recovery of recently deleted files via commands such as MS-DOS’s ‘undelete’. What file shredder might be missing? The problem is that find shredder can wipe only files you will point it to. If you will delete files to Recycle Bin, then file shredder will be able to wipe these files. But when some program silently deletes some temporary files you will not be able to wipe these files, because you even don’t know about them. What possible solutions are? The most simple is using a wipe free space function. Another approach is using background mode file shredder. What are must have features for file shredder? First, it must be secure. Try to use some file recovery tool to make sure wiped files are not available for recovery. Second, it must not require to many clicks. Perfect, if it is integrated with Recycle Bin or better, if it is background mode file shredder. Third, it must have wipe free disk space function. How many times should the file be overwritten Does it matter, if file shredder overwrites data one time or several times? Actually, no, if you are not hiding something really, really, important. It was important 10-years back, when hard disks were slow and did not guaranty the necessary data writing security level.
