Copies a file.
Source or Destination is invalid or not specified.
File is already open.
File does not exist.
See the "Error number" column if you are upgrading Visual Basic 6.0 applications that use unstructured error handling. (You can compare the error number against the Number Property (Err Object).) However, when possible, you should consider replacing such error control with Structured Exception Handling Overview for Visual Basic.
This example uses the FileCopy function to copy one file to another. For purposes of this example, assume that SrcFile is a file containing some data.
