.PBK File Extension

Data file used by the Network Connections utility in Microsoft Windows, which is also referred to as the Remote Access Phonebook; stores saved dial-up connection settings, which include phone numbers, logins, and passwords; can save data for multiple connections.

Program file created by Pixel Bender Toolkit, an Adobe application used for creating custom image filters for programs such as Photoshop and After Effects; contains source code written in the Pixel Bender kernel language, which uses C-like syntax.

The Pixel Bender Toolkit is designed for creating low-level image-processing algorithms that compile efficiently for execution on GPU and CPU multiprocessor systems. The Pixel Bender language allows developers to write highly optimized image manipulation algorithms.

NOTE: PBK files can be compiled into .PBJ files which are filters that are usable by Adobe Flash Player.
