  • Microsoft Windows Software Development Kit (SDK) for Windows versions 3.0 and 3.1

COPYTEST is a sample that contains a complete code module to copy a file of any size and set its file date/time stamp.

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).

Download COPYTEST.EXE, a self-extracting file, from the Microsoft Software Library (MSL) on the following services:

  • Microsoft Download Service (MSDL) 

          Dial (206) 936-6735 to connect to MSDL
      Download COPYTEST.EXE (size: 38565 bytes)
  • Internet (anonymous FTP) 

          ftp ftp.microsoft.com
      Change to the \SOFTLIB\MSLFILES directory
      Get COPYTEST.EXE (size: 38565 bytes)

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.
