Version: 2.0.4 (using 4.1) Compiler: gcc OS: MS Windows Decrypted or signed files should open Kleopatra with the option "open with..." from Windows Explorer. So it whould be possible to define e.g. *.pgp files with Kleopatra to start Kleo with double click at these file types.
Auto-detection-mode for binary files will solve this problem. But it isn't implemented yet. Scheduled for gpg4win 2.0.
This is a packaging thingy, we can register in windows that kleopatra can handle *.pgp files and so on. I'm taking this.
