SecureAction Secure Notes Organizer is an award-winning easy-to-use tool for Windows 95, Windows 98, Windows NT and Windows 2000 with Outlook-like interface which allows you to organize your notes and business data in hierarchical structure.

It is 32-bit (no doubt), written totally in C++, it does not use any database engines and thus is very fast. The database generated by SNO is very compact due to using its own compression engine.
