Thank you for your reply.
I just purchased the software and I am trying to find how this will work out.
On the HDD I store family photos etc. I do need to encrypt every single file when I login, I just need all the files to be encryted so that if the HDD lost, there will be no access to the files by an another person.
The actual encryption will take place per file when I open it.
Is this possible? In general how the software supports the security of a total HDD (as in my case)?.
