Reuse .PBT and .PBI Files
Feature Only in Professional and Enterprise Editions Profiling is supported only in Visual C++ Professional and Enterprise Editions. For more information, see .
For a large program, it can take a lot of time for PREP to create .PBT and .PBI files from scratch. You must rebuild these files if you change your source code or the profiling method, but you can reuse the files if you only need another profile run with different program input data. Just copy the .PBT file after the initial Phase I PREP run. The .PBI file is never changed, so you don’t need to copy it.
