Hello,

I haven't touched C++ in a while and I'd like to get back into it.  I'm now using VC++ 6.0 (a new compiler to me).

I would like to know how I would move all files in directory A to directory B (windows 2000 computer - program run locally) that are older than 5 minutes.

Thanks!

If you're using MFC, you can use the CFileFind class to find the files, then the CTime class to compare the time, and then MoveFileEx to move the file, like:
  CFileFind ff;
  CTime start_time = CTime::GetCurrentTime(); // Get the start time
  if(ff.FindFile("c:\\*.*")) // Find the files under C
  {
    BOOL result;
    do
    {
      result = ff.FindNextFile();

      CTime creation_time;
      ff.GetCreationTime(creation_time); // Get the creation time
      if((start_time - creation_time).GetTotalMinutes() > 5) // If the difference is over 5 minutes
      {
        CString new_file_name = "c:\\backup\\" + ff.GetFileName();
        MoveFileEx(ff.GetFilePath(), new_file_name, MOVEFILE_COPY_ALLOWED | MOVEFILE_REPLACE_EXISTING); // Move the file
      }

    } while(result);
  }

If you're not using MFC, the FindFirstFile and FindNextFile will be the same.  Then you use the ftCreationTime data member to compare against the current time.  It's not quite as easy, but pretty close.  The struction would look the same, except that the FindNextFile stuff would happen after you compared the FindFirstFile stuff, whereas with the MFC version you need to call FindNextFile before using any of the data members.  Good luck.

I guess I don't really know what MFC is.  All I know is i'm using visual C++ 6 and I created a new console application and have one .cpp source code file.  Sorry - Like I said VC++ 6 is a new tool to me.  I understand what your code is doing for the most part and I might be able to figure the problem out from that
