Tryb pracy bez rozr\u00f3\u017cniania wielko\u015bci liter mo\u017cna opcjonalnie w\u0142\u0105czy\u0107 w odniesieniu do poszczeg\u00f3lnych katalog\u00f3w za pomoc\u0105 nowego atrybutu «+F» (EXT4_CASEFOLD_FL). Po ustawieniu tego atrybutu na katalogu, wszystkie operacje na plikach i podkatalogach wewn\u0105trz b\u0119d\u0105 przeprowadzane bez uwzgl\u0119dnienia wielko\u015bci liter, w tym b\u0119dzie ignorowane przy wyszukiwaniu i otwieraniu plik\u00f3w (na przyk\u0142ad, pliki Test.txt, test.txt i test.TXT w takich katalogach b\u0119d\u0105 traktowane jako identyczne). Domy\u015blnie, z wyj\u0105tkiem katalog\u00f3w z atrybutem «+F», system plik\u00f3w nadal jest rozr\u00f3\u017cniaj\u0105cy wielko\u015b\u0107 liter. Aby zarz\u0105dza\u0107 w\u0142\u0105czeniem trybu niezale\u017cnego od wielko\u015bci liter, proponowany jest zmodyfikowany zestaw narz\u0119dzi, e2fsprogs<\/a><\/noindex>.<\/p>\n

\u0141aty zosta\u0142y przygotowane przez Gabriela Krisman Bertaziego, pracownika firmy Collabora, i przyj\u0119te po si\u00f3dmej<\/a><\/noindex> pr\u00f3bie po trzech latach<\/a><\/noindex> rozwoju i usuwania uwag. Realizacja nie zmienia formatu dysku i dzia\u0142a wy\u0142\u0105cznie na poziomie zmiany logiki por\u00f3wnywania nazw w funkcji ext4_lookup() oraz wymiany hasha w strukturze dcache (Cache Wyszukiwania Nazw Katalog\u00f3w). Warto\u015b\u0107 atrybutu «+F» jest przechowywana wewn\u0105trz inode poszczeg\u00f3lnych katalog\u00f3w i stosuje si\u0119 do wszystkich zagnie\u017cd\u017conych plik\u00f3w i podkatalog\u00f3w. Informacje o kodowaniu s\u0105 przechowywane w superbloku.<\/p>\n

Aby unikn\u0105\u0107 kolizji z nazwami istniej\u0105cych plik\u00f3w, atrybut «+F» mo\u017ce by\u0107 ustawiony tylko na puste katalogi w systemach plik\u00f3w, w kt\u00f3rych na etapie montowania w\u0142\u0105czony jest tryb wsparcia Unicode w nazwach plik\u00f3w i katalog\u00f3w. Nazwy element\u00f3w katalog\u00f3w, dla kt\u00f3rych aktywowany jest atrybut «+F», automatycznie s\u0105 konwertowane na ma\u0142e litery i odzwierciedlane w ten spos\u00f3b w dcache, ale na dysku s\u0105 zachowywane w oryginalnej formie podanej przez u\u017cytkownika, tzn. mimo przetwarzania nazw niezale\u017cnie od wielko\u015bci liter, nazwy s\u0105 wy\u015bwietlane i przechowywane bez utraty informacji o wielko\u015bci liter (jednak system nie pozwoli na utworzenie nazwy pliku z tymi samymi znakami, ale w innym rejestrze).<\/p>\n
