Securely delete files with cipher
Anyone who thinks that their files are no longer available after deleting them with the usual procedures is wrong.
Basically, they are just no longer visible and the space they occupied is released.
In normal everyday life this is not a problem either, it only becomes critical when the computer is sold, for example, or even just a USB stick is passed on. In this case you want to make sure that strangers have no access to private information.
Of course there are tools, for a fee and also as freeware, that do this, but Windows also brings a tool that does just that: cipher
This tool has existed since Windows 2000 and is available in all subsequent operating systems such as Windows XP, Windows Vista or even Windows 7.
