I would like to copy a file from one folder to another. I need to be able to specify a full UNC path. What functions, if any, does Vc++ supply to do this?
Thanks for any help;

Try the CopyFile() (or maybe MoveFile() and MoveFileEx()) windows API functions.

Let me know if you have questons.

I've tried these functions but they don't seem to work for what I need.
I'd like to be able to write:
copyfile("\\serv01\directory\file.txt","C:\dest\");
Have I made a mistake, do the files you suggested work for this?

If that is exectly what you had in your code, then the problem is not the function.

You must use two \'s inside a string "literal" to represent a single \.

Thus you would need

copyfile("\\\\serv01\\directory\\file.txt","C:\\dest\\")

Is that the problem?

That'd be the problem.
Sorry, another problem as well:
I tried using two cstrings for the files but it doesn't seem to work. Is there CString member function which will convert the Cstring so that copyfile will work? I can't seem to find one. Thanks.

The CString c;ass has a conversion to LPCSTR operator.  That should be invoked automatically, thus there should be no problem.

Note for this to work, you must specify the CStrign object to the function, not a pointer to one.  The object will be converted to a pointer to a NUL terminated string.  (If you specify a pointer to a CString this won't happen.)
