VC ++ copies the entire folder

Copyfile can only copy one file. to copy all the files in the entire folder, you need to traverse the files in the folder.

Myfile. h

 
# Pragma once # include <string> # include <windows. h> # include <iostream> # include <stdio. h> # include <Io. h> # include <string> # include <shlwapi. h> using namespace STD; Class cmyfile {public: explicit cmyfile (void );~ Cmyfile (void); static void mycopyfile (string sourcefilepath, string destfilepath );};
 

Myfile. cpp

Use

Cmyfile: mycopyfile ("E: \ test1", "E: \ t2 ");
