PowerBuilder Target (PBT) is a configuration file format developed by Sybase and currently maintained by SAP for use within the PowerBuilder integrated development environment. These files serve to define the parameters of a specific software target, including the library list and application object required for project compilation. As configuration files, they are generally considered safe and possess no inherent executable risk, though they remain essential for maintaining legacy enterprise applications.
