+    This is the main project file for VC++ projects generated using an Application Wizard. 
+    It contains information about the version of Visual C++ that generated the file, and 
+    information about the platforms, configurations, and project features selected with the
+    Application Wizard.
+
+uiabtest.vcxproj.filters
+    This is the filters file for VC++ projects generated using an Application Wizard. 
+    It contains information about the association between the files in your project 
+    and the filters. This association is used in the IDE to show grouping of files with
+    similar extensions under a specific node (for e.g. ".cpp" files are associated with the
