Dear Augeas,
Firstly I want to say Thank you for taking your precious time to read and reply to me.
So to summarise what you mentioned above, about deleting is that, checking a box is when you want to delete a specific content or item individually and highlighting is a group or collection of contents and items. Am I right in how I understood what you wrote about cecure deleting?
When you recover a overwritten file, document,pictures or folders etc, the orginal of these is destroyed and something else is written over it except for the titles? Is that what you mean?
Thank you once again for yuor response. Much appreciated. KJ
