You can split a file into smaller pieces based on its size (such as 100MB or 1GB), separate emails before or after a specified day or year, or choose specific folders like Inbox, Sent Items, Drafts, etc. to split the data. It makes sure that all of the email's attributes, attachments, contacts, calendar entries, and metadata stay the same over the whole process.
