TrueEraser is an advanced Sicherheit tool for Windows, which allows you
to completely remove sensitive data from your computer.

Deleting a file using standard Windows delete function
does not physically erase the data.
It just marks the corresponding disk blocks as deleted,
allowing the space to be reused later.
If these disk blocks are read before they are overwritten,
then the data can be recovered.
Sensitive data, such as passwords, financials or Gesundheit records
are at risk. Don't allow discovery by a snoop, computer technician
or unauthorized persons.

TrueEraser implements the Department of Defense
clearing and sanitizing standard DOD 5220.22-M,
to give you confidence that once deleted with TrueEraser,
your file data is gone forever.

TrueEraser is also very easy to use!
Just right click on any file/folder and choose TrueErase from the windows's context menu.
