:) wolne oprogramowanie* :)

7-Zip

7-Zip jest archiwizerem (pakerem) plików o najwyższym stopniu kompresji.

Główne cechy programu 7-Zip przedstawiają się następująco:
* Darmowy program dystrybowany na licencji GNU LGPL
* Najwyższy stopień kompresji przy pakowaniu w nowym formacie 7z
* Obsługiwane formaty: 7z, ZIP, CAB, RAR, ARJ, LZH, CHM, GZIP, BZIP2, Z, TAR, CPIO, RPM i DEB
* Dla formatów ZIP i GZIP 7-Zip ma kompresję 2-10 % wyższą niż w programach PKZip i WinZip
* Samorozpakowujące się archiwum (SFX) dla formatu 7z
* Integruje się z powłoką Windowsa (menu kontekstowe)
* Własny manager plików
* Oferuje plugin dla managera plików FAR
* Linia komend o dużej mocy
* Lokalizacje (tłumaczenia) dla ponad 57 języków


7-Zip działa w Windows 98/ME/NT/2000/XP. Wersja dla linii komend istnieje również dla Linuksa.

7-Zip jest darmowym programem dystrybowanym na licencji GNU Lesser General Public License.

Stopień kompresji jest bardzo uzależniony od rodzaju plików jakie zostały użyte. Zazwyczaj 7-Zip kompresuje do formatu 7z 30-50% lepiej od formatu zip. A także pakując do zip'a 7-Zip robi to o 2-10% lepiej niż inne programy.

Format 7z

7z jest nowym formatem archiwum, o wysokim stopniu kopresji.

Główne cechy formatu 7z:
* Otwarta architektura
* Wysoki stopień kompresji
* Silne szyfrowanie (AES-256)
* Możliwość używania jakiej kolwiek metody kompresowania lub jej modyfikacji
* Obsługuje pliki o rozmiarze do 16000000000 GB
* Obsługa standardu UNICODE w nazwach plików
* Kompresja ciągła
* Kompresowanie nagłówków archiwów

7z ma otwartą architekturę, więc może osługiwać każdą nową metodę kompresji. Na dzień dzisiejszy zaintegrowane do formatu 7z są metody:
Metoda Opis
LZMA Zmodyfikowany i zmodyfikowany algorytm LZ77
PPMD Dmitry Shkarin's PPMdH z małymi zmianami
BCJ Konwerter dla 32-bit x86 wykonywalnych
BCJ2 Konwerter dla 32-bit x86 wykonywalnych
BZip2 Standardowy algorytm BWT
Deflate Zmodyfikowany algorytm LZ77

Algorytm LZMA jest domyślną i główną metodą kompresji formatu 7z. Główne cechy algorytmu LZMA:
* Wysoki stopień kompresji
* Zmienny rozmiar słownika (do 4 GB)
* Szybkość kompresji: ok. 1 MB/s na 2 GHz procesorze
* Szybkość dekompresji: ok. 10-20 MB/s na 2 GHz procesorze
* Małe wymagania pamięci przy dekompresji (zależne od wielkości słownika)
* Nieduża wielkość kodu dla dekompresji (ok. 5KB)
* Obsługuje wielowątkowość (multi-threading) i hyper-threading

7z jest częścią programu 7-Zip dystrybuowanego na licencji GNU LGPL.

Programy, które obsługują archiwa 7z: WinRAR, PowerArchiver, TUGZip, IZArc.

[color="Red"][SIZE="4"]7-Zip 4.44 alpha 1[/SIZE]
By: Igor Pavlov (ipavlovProject Admin) - 2006-12-26 03:43[/color]


7-Zip 4.44 alpha 1 for 32-bit Windows:
http://www.7-zip.org/alpha/7z444a1.exe
http://www.7-zip.org/alpha/7z444a1.msi

7-Zip 4.44 alpha 1 for 64-bit Windows x64:
http://www.7-zip.org/alpha/7z444a1-x64.msi

Don't use this alpha version for important data. Call "Test" command after each compressing operation.

What's new:
- Speed optimizations for LZMA, Deflate, BZip2 and unRAR.
- Some changes in error messages.
- Some bugs were fixed.
- New localizations: Bangla, Bashkir, Nepali.

Details about speed optimizations:
- LZMA in multithreading mode for dual-core CPUs
- BZip2 compressing and decompressing
- Deflate in Max and Ultra modes
- UnRAR code was rewritten. And it must work faster now.

Please check 7-Zip 4.44 for largest data sets (more than 2-4 GB) in solid / ultra mode. Call "Test" command after each compressing operation. Check also 64-bit version of 7z / LZMA for largest data sets more accurately, since MSVC 64-bit compiler has some bugs.

[color="Red"][SIZE="4"]7-Zip 4.44 alpha 2[/SIZE]
By: Igor Pavlov (ipavlovProject Admin) - 2007-01-08 23:39[/color]

7-Zip 4.44 alpha 2 for 32-bit Windows:
:arrow: http://www.7-zip.org/alpha/7z444a2.exe
:arrow: http://www.7-zip.org/alpha/7z444a2.msi

7-Zip 4.44 alpha 2 for 64-bit Windows x64:
:arrow: http://www.7-zip.org/alpha/7z444a2-x64.msi

Don't use this alpha version for important data. Call "Test" command after each compressing operation.

What's new after alpha 1:
- Bug was fixed: 7-Zip 4.44 alpha 1 worked incorrectly with some rare settings: (7z + LZMA + Normal/Max/Ultra + Multi-threading + mf=hc4 in parameters).
- 7-Zip now supports file pathnames longer than 260 characters.
- Some internal changes.

Please note that most programs in Windows (including Windows Shell) doesn't support file pathnames longer than 260 characters. So probably you can work with such files only in 7-Zip File Manager.
