Haddii aad tahay kaydiye faylal, isku-buufinta faylka waa wax ay tahay inaad gabi ahaanba ka ogaato. Inkasta oo tignoolajiyada kaydinta ay sii waddo inay horumariso si xawli ah, hufnaantu weligeed wax xun maaha.

Ma aha in la xuso, qaar badan oo ka mid ah jaangooyooyinkeena faylalka maanta ayaa ka dhigaya kuwii hore - 128 kbps MP3-yada^(MP3s) aan ku soo dejisanay Napster hadda waxaa lagu bedelay FLACs , halkaas oo hal hees ay noqon karto cabbirka album MP3 oo dhan.^(MP3)

Qaar badan oo naga mid ah waxay leeyihiin faylal aynaan doonayn inaan ka takhalusno laakiin sidoo kale uma baahnid galaangal firfircoon oo degdeg ah. Kuwani waxay noqon karaan sawiro, muuqaalo, muusik, iyo qaar kaloo badan. Abuuritaanka kaydka faylalkaas waxay hoos u dhigi kartaa booska diskooga ee la isticmaalay, taas oo markaa, keeni karta waxqabad wanaagsan. Waxa kale oo ay kaydin kartaa jeebabkaaga - 1 TB-gaaga adag ee dibadda waxa uu dareemi karaa in uu kuugu dhow yahay 2 TB haddii aad si sax ah u kaydiso!

Barashada sida loo cadaadiyo faylashaada ma aha mid aad u adag, laakiin ka waran dhammaan qaababkaas kaydka? Cadaadiska feylasha waxay gelinaysaa "sanduuqa" hal fayl, laakiin faylkaas wuxuu yeelan karaa kordhin badan oo kala duwan: ZIP , RAR , 7Z, TAR , GZ - waa maxay^(GZ—what) macnaha kuwan oo dhan? Hubaal waxaa jira farqi, sax?

Dabcan way jirtaa! Haddii ay jiraan hal shay oo PC-gu ku fiican yahay, waxay ku siinaysaa doorashooyin, marka ay timaado kaydinta faylashaada, waxaad haysataa qaar badan oo ka mid ah. Maqaalkan, aan ka wada hadalno faraqa u dhexeeya qaabab badan oo caan ah oo la cufan qaababka kaydinta faylka^{(differences between the many popular compressed file archive formats)} .

Waa maxay kaydka ZIP?

WinZip waa mid ka mid ah kaydiyeyaasha faylalka ugu horreeya ee helay caannimo baahsan, waxayna u oggolaaneysaa isticmaaleyaasha inay ku cadaadiyan faylasha sida kaydka ZIP .

Waa kuwan faraqa ugu weyn ee qaabka ZIP ka leeyahay noocyada kale ee faylka:

• Faylasha waxaa lagu kaydin karaa cadaadis la'aan.
• Fayl kasta oo ku jira kaydka si gooni ah ayaa loo cududeeyey. Tani waxay u ogolaaneysaa isticmaalka algorithms kala duwan iyo saamiga cadaadiska sare laakiin waxay la socotaa cilladda xajmiga faylka weyn ee kaydka marka la cadaadiyo tiro badan oo faylasha yaryar ah.
• Sirta ku salaysan sirta ah ee ZIP waxay ahayd mid daciif ah ilaa 2003 (marka AES lagu daray).
• Ilaa inta kordhintu ka timid, waxaa jiray 4 GB xad adag wax walba: cabbirka faylka aan la cadaadin, cabbirka faylka la cufan, iyo wadarta cabbirka kaydka.
• Isku-buufinta ZIP^(ZIP) waa dhakhso oo maaha sida CPU-degdegga ah sida badi beddelka caanka ah ee maanta.
• ZIP waxaa taageera inta badan Linux qaybinta iyo dhammaan noocyada Windows (tan iyo XP) ee ka baxsan sanduuqa.

Waa maxay kaydka RAR?

WinRAR waxay caan ku noqotay muddada "tijaabada" weligeed dhammaanaysa. 30 maalmood ka dib, waxaad bilaabi doontaa inaad WinRAR^(WinRAR) ka hesho popup sheegaya in tijaabadaadu dhammaatay, taas oo aad markaas uun... xidhi karto. RAR , oo loogu magac daray horumariyeheeda, Eugene Roshal , waa qaab kayd ah oo caan ah oo caan ah maanta.

Waa kan sida ay uga duwan tahay dadkii badnaa:

• RAR waxay u ogolaataa habaynta kaydka kaydka mug, taasoo ah hab wax ku ool ah oo lagu kaydiyo galalka waaweyn.
• Waxa kale oo aad ku cadaadi kartaa faylasha hal block (qaab adag).
• Sireeynta AES waa heer.
• Kaydka waxa lagu ilaalin karaa erayga sirta ah
• Cadaadiska faylalka maqalka ah ayaa si gaar ah waxtar u leh (ilaa 90%).
• Kaydka RAR^(RAR) waxa lagu dhex geli karaa faylal kale. Ma^(Did) ogtahay inaad ku qarin karto kaydka RAR JPEG^{(hide a RAR archive in a JPEG)} ?
• Qaar badan oo ka mid ah hababka soo saarista RAR ayaa dib loo qoray sidii software il furan.
• RAR waxay leedahay saamiga isku xidhka guud ee ka wanaagsan marka la barbar dhigo ZIP , tartanka ugu weyn.

Waa maxay kaydka 7Z?

La yaab ma leh, qaabka kaydka 7Z waxaa keenay barnaamijka Windows 7 ^(Windows)-Zip^(7-Zip) . Taasi waxay ahayd ilaa 1999kii! 7-Zip iyo maktabad lagu akhriyo qaabka faylka 7Z ayaa labaduba si guud looga heli karaa GNU Shatiga Guud ee Guud ee Yar^{(GNU Lesser General Public License)} .

Waa kuwan qaar ka mid ah astaamaha 7Z:

• 7Z waxay leedahay qaab dhismeed kaas oo labadooduba modular ah oo furan, kaas oo u oggolaanaya isku-buufin, beddelaad, iyo sir faylal iyada oo loo marayo habab kala duwan oo wax lagu dhejiyo.
• Faylasha waxaa lagu cadaadin karaa qiyaas ahaan 2-10%.
• Sireeynta AES waa heer.
• Dhammaan madaxyada kaydka waa la cufan Madax-dhaqameedyada kaydiya macluumaadka ku saabsan sida loo maareeyo xogta blocks ee ku jirta kaydka.
• Faylasha aadka u weyn ( balaayiin GB) waa la taageerayaa.
• Algorithms-ka cadaadiska la taageeray ( LZMA/LZMA2 , PPMd , BZip2 ) waxay ka faa'iidaysan karaan xisaabinta isbarbar dhigga ^(BZip2)CPUs-yada^(CPUs) kala duwan ee casriga ah .

Waa maxay kaydka TAR?

TAR waa qaabka faylka ugu caansan ee nidaamka Unix^(Unix) iyo Unix -like. Waa muhiim in la fahmo in TAR kasta uu yahay kaliya fayl kayd ah. Waxa loo istcimaali jiray si la mid ah GZ, kaas oo loo isticmaalo in lagu cadaadiyo faylasha oo aan lahayn awood kaydin lafteeda. Si wada jir ah, waxay abuuraan faylka "tarball" ( qaabka TAR.GZ ).

TAR waxa^(TAR) ay suurta gelisaa helida jawaabaha HTTP oo la isku riixay oo ay dirto codsiyo cufan, taas oo u ogolaanaysa saamiga isku xidhka in uu gaadho ilaa 80%. Qaabka kaydintan waxa inta badan loo adeegsadaa kaydinta iyo qaybinta waxa ku jira dhammaan dhadhanka Linux . Kaydka TAR^(TAR) waxa uu ilaaliyaa oggolaanshaha kooxda, taariikhaha, qaab-dhismeedka hagaha, iyo macluumaadka kale ee nidaamka faylka muhiimka ah.

Sida aad arki karto, qaab kasta oo kayd ahi waxa uu leeyahay faa'iidooyin iyo khasaarihiisa - si xikmad leh u dooro iyadoo ku xidhan nooca faylalka aad ku cadaadinayso iyo ujeedada kaydkaaga. Saamiga cadaadiska^{(Compression)} , xawaaraha, iyo amniga dhamaantood waa mudan yihiin in xisaabta lagu daro, waxaana jira waqti iyo goob mid kasta oo ka mid ah qaababkan!

Differences Between the Many Archive Compressed File Formats

If you’re a file hoarder, file compression is something yоu absolutely must know about. Although storage technology continues to improve at a rapid rate, efficіency is never a bad thing.

Not to mention, many of our file standards today dwarf those of the past—the 128 kbps MP3s we used to download on Napster have now been replaced with FLACs, where a single song can be the size of an entire MP3 album.

Many of us have files that we don’t want to get rid of but also don’t need immediate, dynamic access to. These can be photos, videos, music, and much more. Creating an archive of these files can cut down on used disk space which can, in turn, result in better performance. It can also save your pockets—your 1 TB external hard drive can feel closer to 2 TB if you archive properly!

Learning to compress your files isn’t very hard, but what about all of those archive formats? Compressing files puts them in a “box” of a single file, but that file can have so many different extensions: ZIP, RAR, 7Z, TAR, GZ—what do these all mean? Surely there’s a difference, right?

Of course there is! If there’s one thing PC excels at, it’s giving you options, and when it comes to archiving your files, you have many of them. In this article, let’s discuss the differences between the many popular compressed file archive formats.

What is a ZIP archive?

WinZip is one of the first file archivers that gained widespread popularity, and it allows users to compress files as a ZIP archive.

Here are the main differences that the ZIP format has over other archive file types:

• Files can be stored without compression.
• Each file within the archive is compressed separately. This allows for the use of different algorithms and a higher compression ratio but comes with the drawback of a larger archive file size when compressing a large number of small files.
• ZIP’s password-based encryption was criminally weak up until 2003 (when AES was added).
• Up until extensions came around, there was a 4 GB hard limit to everything: uncompressed file size, compressed file size, and total archive size.
• ZIP compression is faster and not as CPU-intensive as many of today’s popular alternatives.
• ZIP is supported by the majority of Linux distributions and all versions of Windows (since XP) out of the box.

What is a RAR archive?

WinRAR became famous for its never ending “trial” period. After 30 days, you’d begin getting a popup in WinRAR stating that your trial had ended, which you could then just… close. RAR, named after its developer, Eugene Roshal, is an incredibly popular archive format today.

Here’s how it differs from the crowd:

• RAR allows for the modularization of archives into volumes, which is an efficient way to store massive files.
• You can alternatively compress files into a single block (solid format).
• AES encryption is standard.
• Archives can be protected by a password.
• Compression of audio files is especially efficient (up to 90%).
• RAR archives can be embedded within other files. Did you know you can hide a RAR archive in a JPEG?
• Many RAR extraction routines have been rewritten as open-source software.
• RAR has an overall better compression ratio when compared to ZIP, its biggest competitor.

What is a 7Z archive?

Unsurprisingly, the 7Z archive format was introduced by Windows application 7-Zip. That was all the way back in 1999! 7-Zip and a library to read the 7Z file format are both publicly available under the GNU Lesser General Public License.

Here are some of 7Z’s features:

• 7Z has an architecture that is both modular and open, which allows compressing, converting, and encrypting files via various stacking methods.
• Files can be compressed at ratios around 2–10%.
• AES encryption is standard.
• All of the archive headers are compressed. Archive headers store information about how to handle blocks of data within the archive.
• Extremely large (billions of GB) files are supported.
• Supported compression algorithms (LZMA/LZMA2, PPMd, BZip2) can benefit from parallel computing on modern multi-core CPUs.

What is a TAR archive?

TAR is the most popular archive file format on Unix and Unix-like systems. It’s important to understand that each TAR is only an archive file. It’s used in tandem with GZ, which is used to compress files and has no archiving capabilities itself. Together, they create a “tarball” file (TAR.GZ format).

TAR enables receiving compressed HTTP responses and sending compressed requests, allowing compression ratios to reach up to 80%. This archive format is most often used for backup and distributing content across Linux flavors. TAR archives preserve group permissions, dates, directory structures, and other important file system information.

As you can see, each archive format has its pros and cons—choose wisely depending on the type of files you’re compressing and the purpose of your archive. Compression ratio, speed, and security are all worth taking into account, and there’s a time and place for each of these formats!
