Call this member function to determine if the found file is a directory.
BOOL IsDirectory( ) const;
Return Value
Nonzero if successful; otherwise 0.
Remarks
A file that is a directory is marked with FILE_ATTRIBUTE_DIRECTORY a file attribute identified in the WIN32_FIND_DATA structure.
You must call FindNextFile at least once before calling IsDirectory.
See the member function MatchesMask for a complete list of file attributes.
Example
This small program recurses every directory on the C:\ drive and prints the name of the directory.
void Recurse(LPCTSTR pstr)
{
   CFileFind finder;
   // build a string with wildcards
   CString strWildcard(pstr);
   strWildcard += _T("\\*.*");
   // start working for files
   BOOL bWorking = finder.FindFile(strWildcard);
   while (bWorking)
   {
      bWorking = finder.FindNextFile();
      // skip . and .. files; otherwise, we'd
      // recur infinitely!
      if (finder.IsDots())
         continue;
      // if it's a directory, recursively search it
      if (finder.IsDirectory())
      {
         CString str = finder.GetFilePath();
         TRACE(_T("%s\n"), (LPCTSTR)str);
         Recurse(str);
      }
   }
   finder.Close();
}
void PrintDirs()
{
   Recurse(_T("C:"));
}
