I have tried to check "Encrypt content to secure data" (my translate from French), the detail shows my user name. I have then the flag "e" but PSPad 5 opens the file without difficulty.
I have found a reason of the problem. If a drag the file from explorer and drop it to PSPad 5, I have a little question windows "Utiliser du contenu professionel ici ? Votre organisation peut suivre l'action. Voulez-vous vraiment continuer ? Plus d'information Oui / Non" (Translated to english "Use professional content here? Your organization can follow the action. Are you sure you want to continue? More information Yes No") If I use Yes it works. If I click on "More information", it open the browser on Bing on "Supprimer le chiffrement de protection de fichiers professionnels" (Remove professional file protection encryption) Previously I had not this litle question windows because, I choose to open a file from my PSPad Favorite tree (A hart icone before and a star icon now) Regards.
