To get the name of files in a folder,

1. call the FindFirstFile function to open a search handle and get information about the first file that the file system find in the folder.

2. call the FindNextFile function to continue listing files from a previous call to FindFirstFile.

WIN32_FIND_DATA FindFileData;
HANDLE hFind;
TCHAR *FilePathBuff = L"C:\\RequiredFolder";
hFind = FindFirstFile(FilePathBuff, &FindFileData);

if (hFind == INVALID_HANDLE_VALUE)
{
   printf(TEXT("FindFirstFile failed (%d)\n"), GetLastError());
}
else
{
   printf(TEXT("The first file is %s\n"), FindFileData.cFileName);
   while (FindNextFile(hFind, &FindFileData) != 0)
   {
      printf(TEXT("The next file is %s\n"), FindFileData.cFileName);
   }
   FindClose(hFind);
}
