When a fire is put out, it is very important to make sure that the fire is completely out. Embers left behind can flare up and the damage can begin anew. When you put out a fire, you want the fire totally extinguished. This is the same idea behind FILExtinguisher. Typically, data deleted on the computer is not truly deleted. The file stays on the disk until it is overwritten by another file. Until then, those files or file fragments can be recovered. If the data is sensitive, the recovered data could be exploited, causing damage much like the missed ember in a fire. When you delete your data, you want the data totally extinguished. FILExtinguisher offers 14 levels of delete methods from a very fast zero-write to extremely high security NATO level data wiping.
