Windows contains its own set of file I/O functions to perform the basic operations such as file open, close, read, write, and so forth; however, there is no function to copy a file. The COPY.C module included in this sample can be plugged into any application or dynamic-link library (DLL). Some of the features of this module are:

The ability to rename the output file
The ability to copy the file date/time stamp and attributes
Nondependency upon the C run time due to the use of inline assembly
Robust error reporting

For information on how to call the CopyFile() function, please refer to the comment block inside of COPY.C.
