7-Zip


7-Zip is a file archiver with a high compression ratio. This release improves NSIS support and the console version.


7-Zip is capable of recreating the NSIS script, but it has been disabled by default. I've enabled it, along with some improvements. In particular, simple variable assignments are made, which makes more file names available. E.g. a portion of a Big Fish Games installer:

BeforeAfter
$_22_\$_23_$PLUGINSDIR\System.dll
$_22_\$_23_LaunchGame.bfg
$_22_\$_23_pics\60x40.jpg


The console version gains command c to extract to the console (shorthand for combining existing options), along with some more listing options. There's also a new -sub option, intended to substitute text for NSIS variables, but usable with any archive.


7-Zip 16.04a Win32 binary (815k).
