I am not sure why CopyFile is failing. Below is code snippet. Can you help me debug? copyfile fnc returns Zero. permPath is Temp dir loaction on C:\ and I checked it is fine.

if ((hFind = FindFirstFile(L"*", &fd)) != INVALID_HANDLE_VALUE)
      {
            do
            {

            if (wcscmp(CAU_PKG_SIGN_FILE_NAME, fd.cFileName) &&
                        wcscmp(L".", fd.cFileName) &&
                        wcscmp(L"..", fd.cFileName) )
                  {
                        wstring newFileName = permPath + wstring(fd.cFileName);
                        if (!CopyFile(fd.cFileName,(wchar_t*) newFileName.c_str(), FALSE))
                        {
                                                                                          permPath.erase();
                              break;
                        }
                  }
            }
            while (FindNextFile(hFind, &fd));
            FindClose(hFind);
      }

Run it in debug mode, and look at the value of fd.cFileName and newFileName

You should not need to use the (wchar_t*) cast, and I recommend that you remove it.
It only serves to prevent the compiler from doing it's job in type checking.

If you're current working directory is not in the same location as where the file is at, then you'll need to give a full path and file name to CopyFile API for the source.
