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.

PSB

Adobe Photoshop Image File

The PSB (Adobe Photoshop Big) file format is a raster image format developed by Adobe Systems for storing high-resolution images that exceed the size limits of the standard PSD format. It is primarily used in Adobe Photoshop and other compatible graphic design tools for handling large-scale projects such as posters, banners, and high-resolution prints. The PSB format supports layers, transparency, and advanced editing features, making it ideal for professional workflows requiring detailed manipulation of extremely large images.
