Copy, Move, Rename File Preserving Destination Name Case

The CopyFile() and MoveFile() WIN API functions preserve the case of the name for the destination file. Alternatively, WSH can be used. The source and destination file names should include the directory name in both cases.
Note 1 A Copy operation will not change file name case when destination file already exists (overwritten).
Note 2 The WinApiErrMsg is used to retrieve Windows API error message in case of error.
