7Z format and the experimental ARC format provide overall the best compression ratio, with ARC worthing being noticed for excellent compression speed comparable with ZIP format.
ARC, a quite new Open Source archive format introduced by FreeArc (and supported as experimental format both in creation and extraction by PeaZip written ground up for high compression ratio and advanced features like strong encryption and error recovery.
ARC format is impressive for its compression efficiency, both in terms of speed and ratio, but extraction is significantly slower than 7Z format on set 1 where pure extraction performances are more relevant (difference is lower on set 2).
Evaluating, peaZip solely on the basis of its file compression skills, however, it easily matches 7-Zip weight for weight, with context menu integration, portable and.Zipx did not show the impressive compression performances reached on set 1: for both RAR and zipx compression ratio on set 2 was better than ZIP but worse than ARC and 7Z formats.7Z, a popular Open Source archive format introduced by 7-Zip, providing higher compression ratio than RAR, and now supported by many archive managers.Where PeaZip pulls slightly ahead of 7-Zip, however, is in the ease of use and slightly more advanced features it boasts.7-Zip takes the biscuit with its own propriety format, a serous hard hitter when it comes to compression ratio and exportability.File Management, something to bear in mind when looking at PeaZip and 7-Zip, however, is that both also have extensive file management features in addition to their file compression utilities, adding another world of functionality to both.
This set contains various applications for Win32, most common file types are: executables, resource files (icons, graphic and various types of documentation files; applications are from different developers, so different strategies for space optimization and for resource bundling are used.
Zipx format significantly outperformed RAR compression ratio, but compression was twice slower; it even slightly surpassed 7Z compression ratio with twice faster compression time.
In terms of compression ratio, in ideal conditions (set 1 it can be a good match even for 7Z and ARC, but in other conditions (set 2) it provides a compression ratio comparable to RAR.
WinRar scores fastest ZIP compression, and with RAR format compression it reaches improved compression ratio at a reasonable cost in terms of speed.Its a fast, solid app and although 7-Zip is a very worthy competitor, PeaZip just edges it out.In the same situation, in set 1 zipx format extraction shows to be extremely slow, while being only marginally slower than 7Z on set.Composition, set 1 is composed by various standard test files: Calgary and Canterbury corpora, enwik8, Generic compression benchmark, Waterloo sets, containing 134 MB ( B) of data in 71 files and 10 folders.Notes All archivers completed the test without errors.RAR and zipx formats provided a comparable compression ratio on set.Current test compares PeaZip, WinRar, WinZip, IzArc in terms of maximum compression ratio and speed, archiving and extracting files of multiple types (divided in two sets, see below to various archive types: ZIP, widely used archive format, supported for extraction and often creation by most.RAR format shows a clear and consistent advantage in terms of compression ratio over ZIP, with a moderate decrease of speed.In this test RAR format, especially with WinRar, shows generally lower extraction times than other formats including ZIP.7-Zip and PeaZip were reviewed, scored and ranked.There are some interesting security options, allowing you to password protect and encrypt files, manage associated applications, add bookmarks and access gmod 13 parkour gamemode history.By application IZArc provides significantly slower ZIP extraction than the average of other competitors, but achieves average extraction times for RAR and 7Z formats, especially on set.Classic benchmark of speed (in the graph, represented by blue square points) and compression ratio (histogram) over few large files representing various typical data structures.
