What is a PBK file?

PBK files mostly belong to Remote Access Service by Microsoft. PBK files are phonebook files used by the Remote Access Connection Manager (RAS) tool on Windows. RAS uses these files to store information needed for it to establish a remote connection.

  • Structure: PBK files are text files that contain entry names and associated information. They associate the entry names with phone numbers, COM ports, and modem settings. Each entry is a single specified connection.
  • Usage: RAS creates these phone book files themselves. The user can use the "Dial-Up Networking" dialog box to create personal phone book files. The user can also specify the default phone book used when none are explicitly referenced upon establishing a connection. PBK files also allow for easier transfer of connection data by having import/export functionality.
  • VPN: In recent times, PBK files have been more frequently used for, and adapted for, virtual private network connections, since dial-up connections have become very rare.
  • Related associations: PBK can also refer to a plain-text file created by Adobe Pixel Bender. This file is used to store a kernel program.

How to open a PBK file
