Understanding the Concept of Mozilla Thunderbird Data Files

Being a desktop email client, Mozilla Thunderbird has a storage file format that it uses to save all the emails along with attachments. As Thunderbird user, you probably know about MBOX files that stores the mailboxes of Thunderbird. But there are users that work with Maildir files and not MBOX. The difference between MBOX and Maildir is that MBOX stores Thunderbird data as file per mailbox (example: Inbox, Drafts, etc.). On the other hand Maildir stores data in single file per message, i.e., one maildir file is created for each email.
