What is an EMDF file? EMDF is the proprietary database format used by eM Client application to store emails, contacts, calendars, tasks and notes. These files are located in the eM Client data folder (typically C:\Users\[Username]\AppData\Roaming\eM Client\) and cannot be opened by other email clients.

EMDF components supported: Emails with all properties (To, From, CC, BCC, Subject, Date, Body), attachments (documents, images, any file type), folder hierarchy, contacts, calendars, tasks and notes stored in eM Client.

Understanding EMDF
Understanding eM Client's proprietary database format
EMDF is the proprietary database format used exclusively by eM Client to store all mailbox data. Unlike standard email formats (EML, MBOX, PST), EMDF files can only be read by eM Client application or specialized tools like this converter.
EMDF uses a SQLite-based database structure that stores emails, contacts, calendars, tasks and notes in separate data files within the eM Client application folder.
Messages, threads, headers, body content
Documents, images, any file type
Inbox, Sent, Drafts, custom folders
Names, emails, phones, addresses
Events, appointments, reminders
To-do items, memos, notes
