Thank you Svante for you support.
I really understand what you’re saying. But my point is : when I changed my password, I thought it would have changed also the password for my encrypted files. So I shouldn’t remember a password I did forget ;)
The fact is now I have 2 passwords : the new one I’m using to log in and the old one (that I forgot) to manage my encrypt files..
Anyway, I thank you for your time and your support.
