The best way to do this would be to

get into a directory, findfiles and copy them to the destination ONE by ONE. You would want to ignore the "." and ".." files while doing this.

see there is about 50 files and also sub folders in this directory. if i was going to do them one by one. it would take to long:S. The directory is for a program "Retail manager" and i want to back up the whole program just incase something happens to the system with the data.

On Windows you may use code like below:


#include <string.h>
#include <iostream.h>
#include <windows.h>


#define MAX_LEN_CMDLINE                 512
                                       
#define DEF_PROC_ATTR_SEC_DESC_NULL     NULL
#define DEF_THRD_ATTR_SEC_DESC_NULL     NULL
#define DEF_ENV_BLOCK_NULL                       NULL
#define DEF_CUR_DIR_NULL                           NULL
#define INHERIT_HANDLES_FALSE                  FALSE

int main(int nArgs, char* szArgs[])
{
    char szCmdLine[MAX_LEN_CMDLINE] = "xcopy d:\\folder d:\\folder.bck\\ /S /E";

    for (int n = 1; n < nArgs; n++)
    {
        strcat(szCmdLine, szArgs[n]);
        strcat(szCmdLine, " ");
    }

    STARTUPINFO         si;
    memset(&si, 0, sizeof(STARTUPINFO));

    si.cb           = sizeof(STARTUPINFO);
    si.dwFlags      = STARTF_USESHOWWINDOW;
    si.wShowWindow  = SW_SHOWMINIMIZED;

    cout << szCmdLine << "\n";

    PROCESS_INFORMATION pi;
    memset(&si, 0, sizeof(PROCESS_INFORMATION));

    if (!CreateProcess(NULL,
                       szCmdLine,
                       DEF_PROC_ATTR_SEC_DESC_NULL,
                       DEF_THRD_ATTR_SEC_DESC_NULL,
                       INHERIT_HANDLES_FALSE,
                       // DETACHED_PROCESS,
                       CREATE_NEW_CONSOLE,
                       DEF_ENV_BLOCK_NULL,
                       DEF_CUR_DIR_NULL,
                       &si,
                       &pi)
       )
    {
        cout << GetLastError() << "\n";
        return GetLastError();
    }
    cout << "CreateProcess ok pi.hProcess=" << pi.hProcess << "\n";

    // Wait until child process exits.
    WaitForSingleObject( pi.hProcess, INFINITE );

    // Close process and thread handles.
    CloseHandle( pi.hProcess );
    CloseHandle( pi.hThread );

   

      return 0;
}

-----------------------------------------------------------------------

On all  OS you may use  system()



/* SYSTEM.C: This program uses
 * system to xcopy a folder and all its subfolders
 */
#include <process.h>
void main( void )
{
   system( "xcopy d:\\folder d:\\folder.bck\\ /S /E" );
}

----------------------------------------------------------------------

However, in my opinion the copy isn't faster as if you would recursively
make a findfile on all directories and copy all files one-by-one.
