What are PST Files?

In computing, the Personal Storage Table (PST) emerges as an exclusive file format designed by Microsoft. Its purpose is to store duplicates of emails, messages, calendar events, notes, and various other data for its suite of software applications, such as Microsoft Outlook.

The PST file serves as a widely used email storage format in Microsoft's suite. For example, Outlook preserves its data in PST file format. These Outlook PST files are stored in an Outlook file folder located within the documents folder on your computer.
