PST

Personal Storage File

The PST (Outlook Personal Information Store) file format is a proprietary file format used by Microsoft Outlook to store email messages, calendar events, contacts, tasks, and other data locally on a user's computer. It is primarily associated with Microsoft Outlook but can also be accessed using tools like Microsoft Exchange, Outlook Express, and third-party applications such as Kernel for PST Viewer or SysTools PST Repair. The format organizes data in a hierarchical structure, supporting advanced features like encryption, compression, and the ability to store large amounts of data, making it suitable for both personal and professional use.

OTP

Origin Graph Template

The OTP (OpenDocument Presentation Template) file format is a standardized template format used for creating presentations within the OpenDocument family of file formats, maintained by the Organization for the Advancement of Structured Information Standards (OASIS). It is primarily supported by open-source office suites like LibreOffice and Apache OpenOffice, as well as other applications that adhere to the OpenDocument standard. The format is based on XML and supports advanced features such as embedded multimedia, customizable slide layouts, and compatibility with other presentation formats like PPT and PPTX through conversion tools.
