Normally each type of Windows file should have its own default extension, as in .doc for a Word document, .cpp for a C++ file, .cs for a C# file, .exe for an executable file, etc. When you write a Windows program with a Save As option, you should provide a default file extension, and strongly encourage (perhaps even force) your users to save their work in files with that extension. ................
