What is a PBPROJ file?
Development project file created with Project Builder, an IDE originally developed by NeXT but then expanded by Apple for developing Mac OS X applications; used as an older format and is not compatible with Apple's subsequent software development IDE, Xcode.
NOTE: Xcode now uses .XCODEPROJ files for software development projects.
