'' XZ Utils is free general-purpose data compression software with high
|
|
compression ratio. XZ Utils were written for POSIX-like systems,
|
|
but also work on some not-so-POSIX systems. XZ Utils are the
|
|
successor to LZMA Utils.
|
|
|
|
The core of the XZ Utils compression code is based on LZMA SDK, but
|
|
it has been modified quite a lot to be suitable for XZ Utils. The
|
|
primary compression algorithm is currently LZMA2, which is used
|
|
inside the .xz container format. With typical files, XZ Utils
|
|
create 30 % smaller output than gzip and 15 % smaller output than
|
|
bzip2.
