TEST NO. 2
Detection of residual traces in free space
. Download free version of sdelete from Microsoft website : here
. Reset to zero free space with sdelete (use option -z to zero current drive free space)
. Scan the traces in free space with PrivaZer

PrivaZer should detect no trace in the free space.

Comment : a minimum level of traces will always be detected on your C:\ drive.
Because your system continuously creates files, moves files and deletes temporary files in the background.
So you'd better perform the test on a second internal or external drive.
