Unicode in MFC
MFC supports the Unicode standard for encoding wide characters on Windows NT, Windows 2000, and Windows XP platforms. Unicode applications cannot run on Windows 98 platforms.

The Unicode versions of the MFC libraries are not copied to your hard drive unless you select them during a Custom installation. They are not copied during other types of installation. If you attempt to build or run an MFC Unicode application without the MFC Unicode files, you may get errors. |

To copy the files to your hard drive, rerun Setup and click Add/Remove Features. Expand the feature tree Language Tools, then Visual C++, then Visual C++ Class & Template Libraries, and select both ATL MFC Shared Libraries Unicode and ATL MFC Static Libraries Unicode. |

File Types
Import library files have the extension (.lib).
Dynamic-link library files have the extension (.dll).
Module definition (.def) files are text files that contain statements for defining an .exe or .dll.
Map (.map) files are text files that contain information that the linker uses when linking a program.
Library (.lib) files are used in conjunction with the DLL versions of MFC. These files contain code that must be statically linked in the application or DLL.
Program database (.pdb) files contain debugging and project state information.
Debug (.dbg) files contain information (COFF FPO, and CodeView) that the Visual C++ Debugger uses.
