Files and folders deleted by accident, then, can be easily recovered, unless it is physically destroyed from the physical medium. An ordinary deleting of files isn't enough! When you wish to delete any sensitive information, like industrial secrets or some unwanted content, you want to be sure that it will be deleted permanently. Sorry to say, there is a plenty of software recovery tools that can restore your deleted items. If you need to destroy any data and eliminate any possibility of its restoration you need a "shredder". This software destroys the data you choose before the deletion, using a complicated procedure of filling the actual content with random data. This special case of removal is supported by the particular application that completely undermine any hint of presence. All this, for now, thanks to a virtual trash that we are to understand: this is Freeraser.
Freeraser is a digital file shredder that enables you to permanently delete sensitive data with multiple overwrites of random data. It offers a simple overwrite (fast) as well as to DoD 5220.22M (slower) and Gutmann (very slow) compatible deletion methods. The program is very easy to use, it adds a new waste bin icon to your desktop, and any file or folder that you drag onto the bin is permanently deleted and cannot be recovered.
Freeraser can function on three levels:
- A fast destruction (standard 1-round filling of random data)
- A forced destruction (3 rounds of filling according to DoD 5220.22M standard)
- An ultimate destruction (35 rounds of filling with data according to Guttman algorithm).
It is obvious that the more powerful destruction is performed, the more rounds it takes and the more time it needs. Users can define the method that they wish to destroy their data with.
