All known file formats using extension .PBP

While Sony PlayStation Portable Firmware is a popular type of PBP-file, we know of 5 different uses of the .PBP file extension. Different software may use files with the same extension for different types of data.

Phoenix Visual Designer Project

PowerBASIC Project

PowerBASIC Project format (".PBP") is a file used by the PowerBASIC Integrated Development Environment to group together all the source files and related metadata for a particular program under development. It enables saving and restoring the state of a project: which source files are part of it, where they are located, which one is "primary," plus any layout state in the editor.

PowerBASIC creates .PBP files using its IDE via the "Save Project …" command after you open all the source files you intend to use. Later, using "Open Project …" will cause the IDE to load every source file listed inside the project file. The .PBP file is stored in a binary form that the IDE reads to restore its project session.

Internally, .PBP files contain full pathnames of all source code files in the project along with settings such as which file is primary. The file begins with a sequence of zero bytes at offset zero, and has a repeat of space characters (ASCII 0x20) starting at offset 50. These characteristic byte signatures help distinguish the file from other formats using the same extension.
