In the world, there is always someone who is fond of digging other’s private information.

We can delete the files, while they can use file recovery soft wares to recover the files.

In our mind, formatting also called high-level formatting can delete all files permanently

and completely. In fact, it’s not safe. After you format the files, people can

still recover them from your hard disk. The only way to delete files and prevent

people from recovering them is to do low-level formatting. However, this action

will shorten the lifetime of hard disks. Some professional tools say they can

do low-level formatting without damages to hard disks, which is definitely

false. And if you do something wrong in low-level formatting, you can not use

your hard disks any more. So under such situation, our privacy is getting

threatened.

Pulverizer function in Duplicate File Cleaner is different from those tools.

Its theory of operation is adding code to the deleted files. Even people use

file recovery programs, they can’t read the original contents. And this function

will not do any harm to the hard disks. So it can not only protect privacy, but

also the lifetime of hard disks.

Just follow the steps:

1. Run Duplicate File Cleaner, and click “Pulverizer” tab.

2. Click “Add Files” or “Add Folders” to select what you are going to delete. at the bottom
of the interface.

3. Click “Remove Item” to cancel the selected items you have selected.

4. Click “Erase Now” to delete the selected files or folders.
