About .pst Files
PST files are proprietary data files for Microsoft Outlook.
They store emails, calendar events, contacts, tasks, and notes. They work as personal data containers on your computer.
They use the MIME types application/vnd.ms-outlook-pst (for the modern Unicode format) and application/vnd.ms-outlook (for the older ANSI version used from 1997 to 2002).
- Email Storage: They archive and organize emails locally.
- Calendar & Contacts: They hold appointment data and contact information.
- Data Backup: They act as a backup for Outlook data and enable offline access.
- Legacy Support: They include a version from older Outlook releases.
They are mainly used in Microsoft Outlook. Other compatible email tools and backup utilities can also open or convert PST files.
Based on information from FilExt.com, PST files are essential for managing and archiving your personal Outlook data.
Relationship between file extension and MIME type
A file extension is a suffix at the end of a filename that indicates what type of file it is. File extensions help both users and operating systems identify what application should be used to open the file.
File extensions are typically separated from the filename by a period (dot) and consist of 2-4 characters, though they can be longer. For example, in the filename "document.pdf", ".pdf" is the file extension.
File extensions are closely related to MIME types, as they both serve to identify the format of a file. However, while MIME types are used primarily by web browsers and servers, file extensions are used by operating systems and applications.

FAQ
What is a MIME type?
A MIME (Multipurpose Internet Mail Extensions) type is a standard that indicates the nature and format of a document, file, or assortment of bytes. MIME types are defined and standardized in IETF's RFC 6838.
MIME types are important because they help browsers and servers understand how to process a file. When a browser receives a file from a server, it uses the MIME type to determine how to display or handle the content, whether it's an image to display, a PDF to open in a viewer, or a video to play.
MIME types consist of a type and a subtype, separated by a slash (e.g., text/html, image/jpeg, application/pdf). Some MIME types also include optional parameters.
How do I find the MIME type for a file?
You can check the file extension or use a file identification tool such as file --mime-type on the command line. Many programming languages also provide libraries to detect MIME types.
Why can one extension have multiple MIME types?
Different programs and historical usage may assign various MIME identifiers to the same file format. Listing them together helps maintain compatibility across tools.
