File Extension PBP are utilized by Sony PlayStation Portable (PSP) console to launch software such as a firmware update.

But, for those who have no idea what a PSP is, this is a portable playstation handheld entertainment system. So every time an update to PSP is available the EBOOT.PBP function will be downloaded to the system. From there, the system will use the file to update the firmware.
