Data Removal
Here you can select files to be completely removed from the hard disk. The File
Shredder overwrites the data to make recovering the data impossible.
Note: You can also double-click the File Shredder icon on the
desktop to open this function.
Warning: Make sure you select only the information you want to
shred. Once you have shredded a file or folder, it is impossible to
recover the data.
