fast and reliable unzip, unrar, etc tool

(1/3) > >>

kalos:
hello

are you aware of any good unrar, unzip etc tool?
it must be reliable

any benchmarks that prove that its faster?

also, is it true that winrar will always handle better rar files, since its the company that owns rar?

The RAR compression algorithm is proprietary and not licensable. The RAR decompression libraries are available freely. So it depends on what you mean by "better"  ;)

kalos:
better in terms of speed, sys resources consumption, dual or more core utilization, accuracy in data and error tolerance and error fix

f0dder:
I dunno if other companies can do a better job that WinRAR with regards to error tolerance and fixing, but it's possible (although not very likely) that better speeds could be achieved. Only WinRAR will handle compression of RAR archives though, since rarlabs aren't interested in licensing the compression code.

WinRAR is plenty fast and stable though... dunno why you want something "more reliable"? :huh:

Ralf Maximus:
If by "reliability" you mean being able to recover data from an archive, even if it is damaged, check out Parity Archiving:  http://www.par2.net/

Basically, it allows you to create additional "parity" files that contain enough redundancy to rebuild any file or files, no matter how damaged.  The technology can even replace missing RAR files from multi-part archives.

Parity files used with executables can restore the .exe to a pre-virus infection state.

While intended to be used alongside a standard compression tool (Zip, Rar) PAR files can themselves be the archive, albeit with substandard compression.

Very cool, well established technology.
