Privet,
a mozhno link na FTP ?
A voobshe custom sort order - rulez. Konechno esli FTP otobrazhaetsya cherez custom application v webe ili kak-nibud' inache. Esli usaetsya standartnyi FTP server - to moe mnenie rassovat' po tematike/naznacheniyu, i esli vozmozhno vnutri po kompanii proizvoditelyu ili istochniku otkuda prishlo failo. Obosnovano tem, chto chasto ishetsya "takaya shtuchka dlya raboty s XYZ v SQL Server". T.e. esli ya znayu kto pishet nuzhnyi soft ya budu iskat' kompaniyu proizvoditela.
A tak - SQL.RU uzhe tematicheskii server. ;)
