I-ZIP vs 7Z vs ZSTD: Yeyiphi eyona fomati yoxinzelelo yokukopa kunye nokuthumela?

Ukugcina kunye nokuthumela iifayile ezinkulu akuyi kufana ngaphandle koxinzelelo lwezicelo kunye neenkqubo. Ngombulelo kwezi zixhobo, kunokwenzeka ukunciphisa ukuya kwiigigabytes ezimbalwa okanye i-megabytes ukuze kube lula kwaye kulula ukugcinwa okanye ukuthumela. Kodwa yeyiphi eyona fomati yoxinzelelo yokukopa kunye nokuthumela? Kule post, sithelekisa ezintathu: ZIP vs 7Z vs ZSTD kwaye siya kukuxelela xa enye okanye enye ingcono..

Ukukhetha eyona fomati yoxinzelelo yokukopa kunye nokuthumela

Eyona fomati yoxinzelelo yokukopa kunye nokuthumela

Ukunciphisa ubungakanani beefayile zedijithali kubalulekile xa uzigcina okanye usabelana ngazo. Oku kunokwenzeka ngenxa yoxinzelelo, inkqubo esebenzisa i-algorithms ukuya idata yeqela kweyona ntetho incinci inokwenzekaIsiphumo yifayile encinci kakhulu kuneyoqobo, evumela ukuba ithunyelwe ngokulula ngeposi okanye ngezinye iindlela, okanye igcinwe ngaphandle kokuthatha indawo eninzi kakhulu.

Iifayile ezininzi zeefomati ezahlukeneyo zinokucinezelwa zibe yifayile enye enefomathi enye. Kanjalo, Kukho iifomati zoxinzelelo ezahlukeneyo, nganye ineempawu zayo.. Yiyo loo nto kubalulekile ukwazi indlela yokukhetha eyona fomati yocinezelo yokukopa kunye nokuthumela.

Kufuneka kuqatshelwe ukuba iifomati zoxinzelelo azichaphazeli kuphela ubungakanani bokugqibela befayile. Kwakhona imisela i ukuhambelana kunye neenkqubo ezahlukeneyo, kunye ne isantya kunye nomgangatho woxinzelelo kunye noxinzeleloEzinye iifomati zoxinzelelo zigqama ngesantya sazo; abanye ngenxa yokuguquguquka kwabo. Ezintathu zeefomati ezidumileyo nezisetyenziswa kakhulu siya kuzithelekisa kwesi sithuba: ZIP vs. Z7 vs. ZSTD.

ZIP: Umgangatho weHlabathi

Ukukunceda ukhethe eyona ifomathi yoxinzelelo yokukopa kunye nokuthumela, masiqale ngayo endala: ZIPYaphuhliswa ngo-1989 nguPhil Katz, ngokukhawuleza yaba ngumgangatho wokwabelana ngeefayile ezicinezelweyo. Ngamashumi eminyaka yamava, yeyona ifomathi yoxinzelelo eyaziwa kakhulu kwaye isetyenziswa kakhulu.

Inzuzo

Inzuzo yayo ephambili yi ukuhambelana ene: Windows, macOS, Linux, Android, iOS... Zonke iinkqubo zale mihla zokusebenzisa zinokuvula iifayile zeZIP ngaphandle kwesoftware eyongezelelweyo. Ngoko ke, ukuba uthumela ifayile kule fomati, unokuba ne-99,9% eqinisekileyo ukuba umamkeli uya kukwazi ukuyivula.

Enye inqaku elivumayo kukuba i-ZIP icinezela ifayile nganye ngaphakathi kwesikhongozeli ngokuzimeleyoIthetha ntoni le nto? Ukuba uvimba wokugqibela wonakaliswa, kunokwenzeka ukugcina iifayile ezingonakaliswanga ngaphakathi kwayo. Ngesizathu esifanayo, i-ZIP ikuvumela ukuba ukhuphe iifayile ngaphandle kokuvula yonke ipakethe.

Ukushokoxeka

Ifomathi ye-ZIP obona buhle buphambili ikwabubuthathaka bayo obukhulu: kuba indala, isebenzisa ii-algorithms zoxinzelelo ezingasebenziyo. Oku kuthetha ukuba iifayile zokugqibela zinkulu kunezo zinokufunyanwa kusetyenziswa ezinye iindlela zale mihla. Ukongeza, ifomathi ye-ZIP eqhelekileyo ixhasa kuphela iifayile ukuya kuthi ga kwi-4 GB, kuba isebenzisa iidilesi ze-32-bit. Ukucinezela iifayile ezinkulu, kuya kufuneka usebenzise inguqulelo yayo "yangoku", i-ZIP6.

Ngaba i-ZIP yeyona fomati yocinezelo yokukopa kunye nokuthumela?

Ifomathi ye-ZIP lolona khetho lwakho ukuba unenkathalo ngaphezulu umamkeli unokuvula ifayile ngokulula.
Ilungele thumela amaxwebhu, iintetho okanye iifoto ezimbalwa nge-imeyile.
Ikwasebenzela iikopi okanye ii-backups, ukuba nje indawo yokugcina ayiyona nto ibalulekileyo.
Nangona kunjalo, ukuba ujonge uxinzelelo oluphezulu kunye neempawu eziphambili, zama ezinye iindlela.

I-7Z: Ukunyanzeliswa okuphezulu kunye nokuguquguquka

7Zip

Ukuba ujonge eyona ifomathi yoxinzelelo yokukopa kunye nokuthumela, kuya kuba bubulumko ukujonga ifomathi ye-7Z. Le yile ifomathi yemveli yesoftware yasimahla kunye nevulelekileyo I-7-zip, eyaveliswa nguIgor Pavlov ngowe-1999. Kutheni ibalasele nje? Kuba isebenzisa ii-algorithms zoxinzelelo zangoku kunye nobundlobongela, eyona iphawuleka kakhulu yi-LZMA2. Makhe sijonge kwizinto eziluncedo nezingeloncedo.

Inzuzo

Inzuzo ephambili ye-7Z kukuba inika umlinganiselo ophezulu woxinzelelo. Kwiimeko ezininzi, I-7Z ene-LZMA2 ivelisa iifayile phakathi kwe-30% kunye ne-70% encinci kune-ZIPOku kuluncedo olukhulu ukuba uxhasa isixa esikhulu sedatha kwaye ufuna ukugcina indawo yokugcina.

Enye inzuzo ye-7Z kukuba inika iinketho eziphambili, ezifana uxinzelelo oluqinileyo, ekuvumela ukuba ufumane iifayile ezicinezelweyo ezincinci. Kwakhona inenkxaso yeefayile ezinkulu, iinketho zokhuseleko ezifana AES-256 encryption, kunye nenkxaso ye-algorithms yoxinzelelo oluninzi (BZip2, PPMd kunye nabanye).

Ukushokoxeka

Ngokusisiseko, i-7Z inemida emibini emikhulu. Kwisandle esinye, Iisistim ezisebenzayo azinayo inkxaso yemveli yefomathi ye-7Z. Ngamanye amazwi, umamkeli uya kufuna ukufaka inkqubo efana 7-Zip okanye enye yeendlela zayo ezizezinye ukuvula ifayile.

Enye into engalunganga kukuba olu hlobo lwefomathi ifuna ixesha elininzi kunye nezixhobo zoxinzelelo kunye noxinzelelo. Kuyaqondakala, kuba yenye yezona zinto zinamandla ekunciphiseni ubungakanani befayile. Nangona kunjalo, kwiikhompyuter ezindala okanye abo banezibonelelo ezincinci, oku kunokuba yingxaki.

Ngaba i-7Z yeyona fomati yoxinzelelo yokukopa kunye nokuthumela?

Iikopi zifanelekile, ngakumbi ukuba unendawo encinci ukugcinwa.
Kwakhona lukhetho olulungileyo ukuba uyalufuna ukukhusela idatha yakho ngoguqulelo oluntsonkothileyo.
Iphelele ekuthumeleni iifayile okoko nje umamkeli eyazi indlela yokusingatha ifomathi.

I-ZSTD (i-Zstandard): Yangoku kwaye iyakhawuleza

I-ZSTD (i-Zstandard) isenokungabi yiyona ndlela ilungileyo yokucinezela ifomati yokukopa kunye nokuthumela, kodwa isondele. Lo mtsha waphuhliswa nguFacebook (ngoku iMeta) ngo-2015. Ayisiyofomathi yesikhongozeli, njenge-ZIP okanye i-7Z, kodwa i-algorithm yoxinzelelo. Ngoko ke, ayikuvumeli kuphela ukuba wenze iipakethe (.tar), kodwa inokudityaniswa kwezinye izixhobo ze-intanethi, ezifana neeseva, ukuhamba kwedatha, okanye ukugcinwa ngokuzenzekelayo.

Inzuzo

Eyona ngongoma inamandla ye-ZSTD yile isantya esihogweni, ngakumbi kuxinzelelo. Iyakwazi ukukhupha idatha ngesantya segigabytes ngomzuzwana, ngokukhawuleza kakhulu kune-ZIP okanye i-7Z.

Kwinqanaba loxinzelelo, i-ZSTD iyakwazi ukufikelela umlinganiselo kufutshane kakhulu 7Z, kunye nezantya eziphezulu kakhulu. Ikwakuvumela ukuba ukhethe isantya sokucinezela ukubeka phambili ingqibelelo yedatha.

Ukushokoxeka

Ekubeni iyeyona intsha, ine- ukuhambelana okusezantsi kakhulu kunayo nayiphi na enye. Ngapha koko, inenkxaso engcono kwiLinux kuneWindows kunye neMacOS, apho isoftware ekhethekileyo okanye imigca yomyalelo ifuneka ukuyilawula. Ngezizathu ezifanayo, kunjalo ayikho intuitive kakhulu kumsebenzisi ophakathi.

Ngaba i-ZSTD yeyona fomati yocinezelo yokukopa kunye nokuthumela?

Ukuba ujonge ubuninzi speed, I-ZSTD yeyona fomati yocinezelo yokukopa kunye nokuthumela.
Igqibelele ukuxhasa abancedisi okanye oovimba beenkcukacha.
Ilungele ukuhanjiswa kweepakethe zesoftware.
Olona khetho lulungileyo loxinzelelo olukhawulezayo kunye noxinzelelo kwiindawo zophuhliso.

Oko ndandimncinci kakhulu bendinomdla kakhulu malunga nayo yonke into enxulumene nenkqubela phambili yesayensi kunye nezobuchwepheshe, ngakumbi ezo zenza ubomi bethu bube lula kwaye bumnandi. Ndiyakuthanda ukuhlala ndisazi ngeendaba zamva nje kunye nentsingiselo, kunye nokwabelana ngamava am, izimvo kunye neengcebiso malunga nezixhobo kunye nezixhobo endizisebenzisayo. Oku kwakhokelela ekubeni ndibe ngumbhali wewebhu kancinane kwiminyaka emihlanu eyadlulayo, ngokuyintloko egxile kwizixhobo ze-Android kunye neenkqubo zokusebenza zeWindows. Ndiye ndafunda ukuchaza ngamazwi alula into entsonkothileyo ukuze abafundi bam bayiqonde lula.
