It is easy to convert Maildir files to MBOX files. The Softaken Maildir Converter Tool is what I recommended utilizing to convert Maildir to MBOX. Its user-friendly interface (UI) makes it possible for non-technical users to utilize the application. The Maildir Converter is a reliable tool. All of Maildir's email components--including hyperlinks, inline graphics, BCC, and CC--are exported to a specified file type during conversion. No matter the file format or size, attachments are exported. All Windows versions, including Windows 11, 10, 8.1, 8, 7, and all previous versions, are compatible with the software. You can install and utilize the latest demo version of this software.
