So fire up a DOS prompt and type in:
C:\path to my code\>dir *.cpp *.h *.vcproj
/b /s /a:-r > \usafipd\updated_files.txt
This says "list all of the code files and Visual Studio project files from here on down that are writeable (i.e. not locked by Razor), then dump the results to a file in case there are hundreds of filenames to review.
This gives me a file, updated_files.txt, containing a nice list of all the .cpp, .h and .vcproj (Visual Studio project) files I checked out (i.e. made writeable).
