A Personal Folder File is used by Microsoft Outlook to store e-mails and other things. There are three varieties, which exist in 32 and 64 bit varieties:

  • Personal Address Book (PAB) - stores contacts/address book entries
  • Personal Storage Table (PST) - has mailboxes and other things such as tasks, notes, and appointments
  • Offline Storage Table (OST) - is used for offline storage of items from a remote Exchange server
  • Group Storage File (NST) - stores your Groups conversations and other local Groups data

The name "Personal Folder File" actually originally applied to the PST variety, but has been used as an "umbrella" name for all the varieties as well.
