What is an EDFW file? An EDFW file is an electronic diary created by Efficient Software Efficient Diary. It contains text, graphics, and other information that a user has added to their diary. EDFW files can be opened in Efficient Diary but are protected by a password.

More Information Efficient Diary is a Windows program that allows users to keep a password-protected diary. When a user first launches Efficient Diary, the program creates a file named MyDiary.edfw . This is a user's default diary. Users can also create custom diary files, which are saved as EDFW files. EDFW files can contain text, images, tables, and attachments. Users can also store EDFW files on Efficient Diary's cloud server, if they do not want to store their diary on their computer. NOTE: Efficient Software discontinued the Efficient Diary application.
