It is a very usual event in our daily life that we often save and delete the files in the computer. We delete the files without bothering that the file has been deleted permanently or not. Generally, we press “delete” key to delete the files, when we do so the files are moved to recycle bin. On the other hand, when we press “Shift+Delete” key the files are removed from view completely. Similarly, putting a file into the trash and then removing it does the same and never removes the file permanently. In all these cases, the files are not permanently removed from the hard drive and can be recovered with efficient file recovery software. The problem becomes serious for confidential and sensitive documents which can be recovered and accessed by unauthorized users if they are not permanently deleted.
When we delete a file permanently then space occupied by the file is treated as free space and becomes available for storing another data. If the files are not erased permanently, then the deleted files can be restructured and can be recovered. Any smart recovery program can retrieve the data if the files are not properly removed and their contents are not overwritten by the operating system. You will require overwriting the contents of the file in order to delete the files permanently so that they can go beyond the reach of recovery software. If you clean or format the hard drive, your data becomes permanently deleted and nobody could access them. Another efficient approach is to implement a good file eraser software to ensure that the files have been removed permanently and cannot be recovered with data recovery software.
In order to delete file we can employ two kinds of software mechanism which are as follows:
1. Software which completely wipes out data is quite similar to formatting hard drive. This mechanism can permanently delete deleted files along with various other files which are currently running on the computer. You have to make some backup of those crucial files which are deleted along with the files which are intended to be deleted.
2. Another type of mechanism involves the process of deletion which is intended for single files. In this technique, the software keeps all other files in the machines and the user need not to reinstall them after file deletion. This tool basically writes over the file several times with random data which minimizes the chances of recovery of those data. This kind of approach is referred as file shredding.
File shredding is the smarter mechanism by which you can delete the files permanently with an assurance of making them unreachable to recovery tools. The software that is associated with file shredding technique is called file shredder. With the use of file shredder you can assure that the files are permanently removed which cannot be recovered back. There are various file shredder software available today which can ideally be used to delete files.
