Welcome to the P7ZIP Home

P7ZIP

p7zip is a port of 7za.exe for POSIX systems like Unix (Linux, Solaris, OpenBSD, FreeBSD, Cygwin, AIX, ...), MacOS X and also for BeOS and Amiga.

7za.exe is the command line version of 7-zip, see http://www.7-zip.org/.

7-Zip is a file archiver with highest compression ratio.

Since 4.10, p7zip (like 7-zip) supports little-endian and big-endian machines.

J7Zip

J7zip is a JAVA port of 7zr.exe

2007-02-04 : support BCJ filter

2006-12-10 : First public version (support only extracting files compressed with LZMA and BCJ2 filter)

TODO : creating archives, support encryption, support multi-thread, ...

JAVA LZMA SDK

For the fun, I also port the LZMA Decoder from LZMA SDK 4.03 to JAVA.

2005-09-11 : JAVA port of LZMA Encoder and Decoder from LZMA C# SDK 4.23.
