Feshene ea Kabohelo ea Fat (FAT) ke mokhoa oa faele o entsoeng ke Microsoft ka 1977.
FAT e sa ntsane e sebelisoa kajeno e le mokhoa o khethiloeng oa faele bakeng sa koloi ea li-floppy media le portable, lisebelisoa tse phahameng tsa ho boloka matla joaloka li-flash drive le lisebelisoa tse ling tsa mohopolo o tiileng joaloka likarete tsa SD.

Mona ho na le lintho tse ngata liphetolelong tse fapaneng tsa FAT file system:
FAT12 (Letlapa la Likarolo Tsa Leqephe la 12-bit)
Ntho ea pele e sebelisoang haholo ea FAT file system, FAT12, e ile ea hlahisoa ka 1980, hammoho le liphetolelo tsa pele tsa DOS.
FAT12 e ne e le mokhoa o moholo oa feshene bakeng sa mekhoa ea ts'ebetso ea Microsoft ho fihlela ka MS-DOS 3.30 empa e boetse e sebelisoa mekhoeng e mengata ho fihlela ka MS-DOS 4.0. FAT12 e ntse e le tsamaiso ea file e sebelisetsoang floppy disk eo u tla e fumana kajeno.
FAT12 e tšehetsa boholo ba likoloi 'me e fana ka boholo bo ka bang 16 MB ho sebelisa lihlopha tse 4 KB kapa 32 MB ho sebelisa 8 KB, e nang le palo e kholo ea likopi tse 4,084 ka tekanyo e le' ngoe (ha u sebelisa lihlopha tse 8KB).
Ho kenya mabitso tlasa FAT12 ho ke ke ha fetela moeli o ka sehloohong oa batho ba 8, hammoho le 3 bakeng sa katoloso .
Litšobotsi tse 'maloa tsa faele li ile tsa qala ho tsejoa FAT12, tse kenyeletsang, ho bala-feela , tsamaiso , le lebokose la boholo .
Tlhokomeliso: FAT8, e hlahisitsoeng ka 1977, e ne e le eona phetolelo ea pele ea FAT ea tsamaiso empa e na le tšebeliso e fokolang feela le mekhoeng ea lik'homphieutha tsa nako eo.
FAT16 (Lenane la Kabo ea Fumaneha ea 16-bit)
Ts'ebetsong ea bobeli ea FAT e ne e le FAT16, e qalisoa ka 1984 ho PC DOS 3.0 le MS-DOS 3.0.
Phetolelo e ntlafalitsoeng haholo ea FAT16, e bitsoang FAT16B, e ne e le eona mokhoa o ka sehloohong oa faele oa MS-DOS 4.0 ho fihlela ka MS-DOS 6.22. Ho qala ka MS-DOS 7.0 le Windows 95, phetolelo e ntlafalitsoeng e bitsoang FAT16X, e ile ea sebelisoa ho e-na le hoo.
Ho itšetlehile ka mokhoa oa ts'ebetso le boholo ba lihlopha tse sebelisitsoeng, boholo ba koloi bo boholo ba koloi ea FAT16 e ka etsoa ho tloha ho 2 GB ho fihlela ho 16 GB, e leng feela ka Windows NT 4 e nang le lihlopha tse 256 KB.
Finyella boholo ba motlakase oa FAT16 ho tsoa ho 4 GB ka Tšehetso e kholo ea Files e nolofalitsoeng, kapa 2 GB ntle ho eona.
Nomoro e kholo ea lifaele tse ka tšoareloang ka lekaneng la FAT16 ke 65,536. Feela joaloka FAT12, mabitso a faele a ne a lekanyelitsoe ho batho ba 8 + 3 empa a fetisetsoa ho litlhaku tse 255 ho qala ka Windows 95.

FAT32 (Letlapa la Likarolo Tsa Leqephe la 32-bit)
FAT32 ke phetolelo ea morao-rao ea tsamaiso ea FAT ea faele. E ile ea hlahisoa ka 1996 bakeng sa basebelisi ba Windows 95 OSR2 / MS-DOS 7.1 'me e ne e le eona mokhoa o ka sehloohong oa feshene bakeng sa liphetolelo tsa Windows ea bareki ka Windows ME.
FAT32 e tšehetsa boholo ba koloi ea maoto ho fihlela ho 2 TB kapa esita le ka holimo ho 16 TB le lihlopha tse 64 KB.
Joalo ka FAT16, faele ea boholo ba lisebelisoa tsa FAT32 e tsoa ho 4 GB ka Tšehetso e kholo ea Files kapa 2 GB ntle ho eona. Phetolelo e fetotsoeng ea FAT32, e bitsoang FAT32 + , e tšehetsa lifaele tse ka bang 256 GB ka boholo!
Ho fihlela lifilimi tse 268 173 300 li ka ba le molumo oa FAT32 hafeela e sebelisa lihlopha tse 32 KB.
ExFAT (Lethathamo la Tlhaloso ea Lifilimi Tse Eketsehileng)
ExFAT, e qalileng ho tsejoa ka 2006, ke mokhoa o mong oa faele o entsoeng ke Microsoft le hoja e se "FAT32" e latelang "FAT32".
ExFAT e ka sehloohong e reretsoe hore e sebelisoe lits'ebetsong tsa mecha ea phatlalatso tse kang li-flash drive, likarete tsa SDHC le SDXC, joalo-joalo.
ExFAT e tšehetsa ka mokhoa o amohelehang lisebelisoa tsa ho boloka mecha ea phatlalatso ho fihlela ho 512 TiB ka boholo empa theory e ka tšehetsa li khanna tse kholo tse 64 ZiB, tse kholo ho feta tse ling tsa mecha ea litaba tse fumanehang ka mokhoa ona.
Tšehetso ea matsoho bakeng sa li-filename tsa maele a 255 le ts'ehetso bakeng sa lifilimi tse ka holimo ho 2 796 202 ka mongolo o mong le o mong ke likarolo tse peli tsa bohlokoa tsa tsamaiso ea exFAT.
Sesebelisoa sa file ea exFAT se tšehetsoa ke hoo e batlang e le liphetolelo tsohle tsa Windows (batho ba baholo ba nang le litlhaloso tsa khetho), Mac OS X (10.6.5+), hammoho le litabeng tsa TV, mecha ea phatlalatso le lisebelisoa tse ling.
Ho Fumella Li-Files ho tloha NTFS ho ea FAT Systems
Tlhaloso ea khokahano, ho hatella ha faele , ntho e lumelloang, disk quotas, le mekhoa ea faele e baliloeng e fumaneha tsamaisong ea faele ea NTFS feela - eseng FAT . Litšoaneleho tse ling, joalo ka tse tloaelehileng tseo ke li buileng lipuisanong tse ka holimo, li fumaneha le NTFS.
Ba fapane ka liphapang tsa bona, haeba u beha faele e kentsoeng ka lebokose la NTFS ho ea sebakeng se entsoeng ka FAT, file e lahleheloa ke boemo ba eona ba ho patala, e bolelang hore file e ka sebelisoa joaloka feshene e tloaelehileng, e sa ekoang. Ho hlahisa faele ka tsela ena ho ka khoneha feela ho moqapi oa pele ea kentseng faele, kapa motho ofe kapa ofe ea sebelisang tumello ea mohala oa pele.
E tšoanang le lifaele tse kentsoeng, kaha FAT ha e tšehetse ho hatelloa, faele e hatelitsoeng e senyeha ka ho feletseng haeba e ngotsoe ka har'a lekaneng la NTFS le ho feta ka tekanyo ea FAT. Ka mohlala, haeba u kopitsa faele e hatelitsoeng ho tloha ka har'a disk drive ea NTFS ho floppy disk ea FAT, faele eo e tla ikemolla ka ho feletseng pele e bolokiloe ho floppy hobane FAT file ea tsamaiso ea libaka tsa litaba ha e na bokhoni ba ho boloka lifaele tse hatelitsoeng .
