Question : How do I copy files?

Good-day,

I am looking to copy files in C++ without using MFC and am having some troubles figuring out.  

For instance, how would I copy all of the *.txt files from the directory c:\folder1 to c:\anotherFolder ?

Thanks very much for your time, any help would be much appreciated.

Answer : How do I copy files?

I'm not sure how to get the above code working. This is code I use to access web pages. It's third or fourth generation and pretty robust. This is a complete code module.

' clsInternetConnection
'
' Class provides functionalty to read web pages.
'
' Implemented as a class module for use with any VB or VBA project.
