how to find whether give ftp path is file or directory using wininet api?

hi,
Can anyone please let me know how to find whether the given ftp path is file or directory using wininet api? actually i have written ftp client by using wininet api. by using winiet api i am not able to get permissions. when listing files, there will be some link files or directories. i need to findout whether that link file is link to the directory or file. so, if i give some ftp path, i need to know whether that is file or directory? how should i get this?
i am doing this by using ftpfindfirstfile. but is there any other way of doing this?

regards
