Developer file created by Visual Studio, a software development IDE; saves summary data collected from analyzing a performance report (.VSP file); enables the data to be saved without having to re-generate it again from the VSP file. VSPS files are generated by the Visual Studio Profiler. To save a VSPS file in the Profiler, right-click a VSP report and choose "Save Analyzed..." from the drop down menu. NOTE: VSP files may be very large in size. Therefore, developers sometimes keep VSPS files locally while deleting or archiving VSP files.
