Linux Mint Xfce Secure Delete file (Secure-delete)

1, the problem background

As we all know, the deletion of the system actually did not erase the real data.

Only marked for deletion, you can use the empty resource.

As long as the real content is not occupied, some recovery tools can be used to recover these files.

But then there was a problem, and there was a risk for documents with higher confidentiality requirements. How can you guarantee the security of your data?

The method is actually to put the contents of the file space before the deletion of all the other content, it can be.

2. Installation and configuration of Secure-delete

Secure-delete can help us safely remove files and play the role of Shredder.
