Listing files in a directory and saving the filelist + mod_time ( datetime ) to a file

using namespace System;
DateTime dt;
fstream file;
 
file.open(str_RPUFile.c_str(), ios::trunc);
 
// Enumerate all the files/subdirectories
while (true) { 
		dt.FromFileTime(FindFileData.ftLastWriteTime);
		
		if ((FindFileData.cFileName != wstring(L".")) && (FindFileData.cFileName != wstring(L".."))) {
			file << FindFileData.cFileName << L":" << dt.ToLongDateString << L":" << endl;
		}
}
