What is the PST and EML file format?
What is a PST file?
PST (Personal Storage Table) is a proprietary file format used by Microsoft Outlook to store data. It stores mailbox information locally and contains:
· Emails
· Attachments
· Contacts
· Calendar
· Notes
· Journals
PST files are commonly used to back up Outlook, archive mailboxes and move Outlook data from one computer to another.
What is an EML file?
EML is a standard file format for email supported by many desktop email applications. An EML file contains one email message, which includes:
· Email message
· Sender and recipient information
· Enclosures
· Subject lines
· Headings
· Information on date and time
The EML files are supported by many applications such as Thunderbird, Windows Mail, Apple Mail, eM Client, SeaMonkey and a number of forensic and document management applications.
PST to EML conversion improves email portability and allows users to migrate Outlook data to multiple email platforms.
Why Use Dedicated PST to EML Converter Software?
Outlook has migration facilities but it does not have any direct option to convert complete PST mailbox to EML format. Professional converters help users to:
· Convert multiple PST files at once
· Preserve folder structure
· Preserve email metadata
· Convert attachments safely
· Selective mailbox migration
· Reduce manual migration time
