File I/O problem

Hello Experts

I am attempting to write a code that copies files from one location to another.  This is what Iv come up with so far.

#include <Windows.h>
#include <tchar.h>
#include <stdio.h>
#include <iostream.h>
#include <conio.h>
#include <string>
#include <fstream.h>

using namespace std;


int _tmain(int argc, TCHAR *argv[])
{
   WIN32_FIND_DATA FindFileData;
   HANDLE hFind = FindFirstFile("C:\\Data\\*.txt", &FindFileData);      //Get all files in directory "C:\Data"
   int count = 0;
   std::string mstr = " ";
   std::string file_path = " ";
   std::string file_path_dest = " ";
   std::fstream infile,outfile;
   std::string tempstr= " ";  
   char c_string[1000] = {"\0"};
 
  for(int i=0;FindNextFile(hFind,&FindFileData) != 0 ; i++)      
  {  
        mstr = FindFileData.cFileName;      //Get name of next file
       
        file_path = "C:\\Data\\";       //Reload Original path into variable
        file_path_dest = "C:\\Data\\Office\\Work Related Documents\\";
       
        file_path += mstr;            
        file_path_fixed +=  mstr;
         
           infile.open(file_path.c_str(),std::ios::in);
           outfile.open(file_path_fixed.c_str(),std::ios::out);
                     
           while(infile.getline(c_string,1000,'\n'))            //THIS DOES NOT EXECUTE AFTER FIRST FILE IS PROCESSED
           {
               //Make changes at relevant positions of the file
           
            tempstr = c_string;
           
            outfile<<tempstr<<endl;      //Write line to new file      
           }
           
           infile.close();      
           outfile.close();
         
        count++;
   }
   
   FindClose(hFind);
   
   getch();
   return 0;
}

Trouble is, this code only works for the FIRST file only but it does not read/open the second file onwards.  When I check destination folder (C:\\Data\\Office\\Work Related Documents\\), all files are present but have a size of 0KB.....Any assistance will be highly appreciated.

Thank you
