Here you can select folders and files for encryption or decryption. You
can protect your folders and files from being modified, read, or
even accessed without Windows Hello authentication.

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.

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.
