Introduction
Handling multiple EML files is pretty simple, until you start getting lots of duplicates. This occurs from combined email backups, importing the same mailbox multiple times or copying EML files between different systems. The more duplicate messages pile up, the bigger your email archive gets, the longer searches take and the harder it is to find important conversations.
Not all users want to delete duplicate emails manually, but they quickly realize this is a long and risky process. It’s easy to worry about accidentally deleting the wrong email or messing up the organization of folders, especially if you are working with hundreds or thousands of EML files.
Fortunately, there are reliable methods to remove duplicate emails from multiple EML files simultaneously without affecting your original data. This guide reviews the available methods, their pros and cons, and how professional software can make bulk duplicate removal simple while maintaining your email integrity.
