When you deploy a .NET application project, PowerBuilder creates a build directory under the directory for the current target.
The name of the build directory is TargetName.pbt_build, where TargetName is the name of the current target. If the project you deploy has a debug build type, the build files are generated in a “debug” subdirectory of the TargetName.pbt_build directory. If the project you deploy has a release build type, the build files are generated in a subdirectory named “release.”
The debug and release subdirectories store incremental build results only. PowerBuilder does a full rebuild if files are missing or damaged in one of these subdirectories. The subdirectories or their parent directory cannot be used for a project's output path or working path.
In addition to the debug and release directories, PowerBuilder creates a deploy directory when you first deploy a project from the current target. The deploy directory contains an XML file for each project in the target that you deploy.
