What are EML and ZIP files?

EML is a standard file format that is used to store single email messages with all data such as body, sender & recipient details, subject and more. This format is commonly supported by email clients like Outlook, Thunderbird, eM Client and Apple Mail. As it saves each email separately, this makes it difficult for users to manage large volumes of data.

On the other hand, ZIP is a compressed archive file format that is used to combine multiple files into a single file. It helps to reduce file size and storage space which further help users to easily manage data or save for future at one place. ZIP files are widely used by all operating systems and can also be password protected for more advanced security.
