Suurte v\u00f5i v\u00e4ikeste t\u00e4htede ignoreerimise re\u017eiim saab valikuliselt aktiveerida eraldi kataloogide jaoks uue atribuudi '+F' (EXT4_CASEFOLD_FL) abil. Kui see atribuut on m\u00e4\u00e4ratud kataloogile, siis k\u00f5ik failide ja alamkataloogide toimingud toimuvad ilma t\u00e4htede suuruse arvesse v\u00f5tmiseta, sealhulgas ignoreeritakse suurust failide otsimisel ja avamisel (n\u00e4iteks kataloogides peetakse faile Test.txt, test.txt ja test.TXT samaks). Vaikimisi, v\u00e4lja arvatud '+F' atribuudiga kataloogid, on failis\u00fcsteem siiski suurustundlik. Suuruse ignoreerimise re\u017eiimi lubamiseks on ette n\u00e4htud modifitseeritud t\u00f6\u00f6riistade kogum e2fsprogs<\/a><\/noindex>.<\/p>\n

Patchid on ette valmistanud Gabriel Krisman Bertazi, Collabora ettev\u00f5tte t\u00f6\u00f6taja, ja need on aktsepteeritud seitsmenda<\/a><\/noindex> katse j\u00e4rel p\u00e4rast kolme aasta m\u00f6\u00f6dumist.<\/a><\/noindex> arendamiseks ja vigade k\u00f5rvaldamiseks. Teostus ei muuda ketta salvestusformaati ja t\u00f6\u00f6tab ainult nime v\u00f5rdlemise loogika muutmise tasemel ext4_lookup() funktsioonis ja raku hash'i asendamisel dcache'is (Directory Name Lookup Cache). Atribuudi '+F' v\u00e4\u00e4rtus salvestatakse eraldi kataloogide inode'idesse ning kehtib k\u00f5ikide alafailide ja alamkataloogide kohta. Teave kodeerimise kohta talletatakse superplokis.<\/p>\n

Kuna nimi v\u00f5ib p\u00f5hjustada kollisioonide v\u00e4ltimiseks saab atribuut '+F' m\u00e4\u00e4rata ainult t\u00fchjatele kataloogidele failis\u00fcsteemides, kus mountimise etapis on aktiveeritud Unicode toetamine failide ja kataloogide nimedes. Katalooge, millele on aktiveeritud atribuut '+F', nimi muudetakse automaatselt v\u00e4ikeseks t\u00e4heks ja kuvatakse sellisena dcache'is, kuid kettale salvestatakse need algses, kasutaja m\u00e4\u00e4ratud vormingus, st vaatamata sellele, et nimesid t\u00f6\u00f6deldakse suurust ignoreerivalt, kuvatakse ja salvestatakse nimesid ilma t\u00e4he suuruse teabe kadumiseta (kuid s\u00fcsteem ei luba luua faili nime, kus on samad t\u00e4hed, kuid erinevas suuruses).<\/p>\n
