The top two spots are held by an archiver I've never heard of, SBC. Its scores of 1871 (Good) and 1983 (Best) rank third and fourth out of 200.
#WINRAR WINZIP ARCHIVE#
The basic idea is a compressor X has the same efficiency as compressor Y if X can compress twice as fast as Y and resulting archive size of X is 10% larger than size of Y.Īnd sure enough, if you sort the results by efficiency, WinRAR rises directly to the top.
The most efficient (read: useful) program is calculated by multiplying the compression time (in seconds) it took to produce the archive with the power of the archive size divided by the lowest measured archive size.Ģ ^ (((Size/SmallestSize)) - 1) / 0.1) * ArchiveTime The author measured both compression size and compression time to produce an efficiency metric: Consider this recent, comprehensive multiple file compression benchmark.
#WINRAR WINZIP RAR#
When I compressed all the C# code snippets, the difference was enormous:īut even in an apples-to-apples comparison, RAR offers some of the very best "bang for the byte" of all compression algorithms. This is a big deal, because it can result in a substantially smaller archive when you're compressing a lot of files.
RAR also supports solid archives, so it can exploit intra-file redundancies. If you're worried the person on the receiving end of the archive won't have a RAR client, you can create a self-extracting executable archive (or SFX) at a minimal cost of about 60 KB additional filesize. It produces much smaller archives in roughly the same time. But you should use it, because RAR, as a compression format, clobbers ZIP. WinRAR fully supports creating and extracting ZIP archives, so choosing WinRAR doesn't mean you'll be forced into using the RAR compression format. It's frequently updated with neat little feature bumps and useful additions two I noticed over the last year were dual-core support and real-time stats while compressing, such as estimated compression ratio and predicted completion time. And WinRAR is very much a living, breathing piece of software. There's a reason WinRAR won the best archive tool roundup at DonationCoder. In contrast, WinRAR is full-featured, powerful, and integrates seamlessly with the shell. I particularly dislike the limited "compressed folder wizard" I get by default in XP and Vista. Sure, ZIP support is built into most operating systems, but the support is rudimentary at best. WinRAR has become increasingly essential to my toolkit over the last year, so this month, I'm buying a WinRAR license.
#WINRAR WINZIP SOFTWARE#
The countless number of options, as well as its versatility and ease, make it a must-have for any user.When I wrote Today is "Support Your Favorite Small Software Vendor Day", I made a commitment to spend at least $20 per month supporting my fellow independent software developers. Winrar is probably the best compression tool out there. Finally, you can also protect files using Rijndael (AES-128) encryption system, digital signature or protect it against modifications. Plus, Winrar offers a very good compression ratio (above the average), which means that the files you compress will be smaller than compressing them using other programs. Then, choose whether to unpack it or run the files without having to unpack it previously. Just double-click the icon and the content of the file will appear on the screen.
Regardless of the compressed file's format, you can unpack more than 40 different formats, including CAB, ARJ, LZH, TAR, GZ, ACE, UUE, BZ2, JAR, ISO, RAR, Zip or 7Z.
#WINRAR WINZIP PASSWORD#
You can also add a password or a comment. The program integrates itself perfectly in the right-button menu, so you can easily create RAR and ZIP files. Winrar is a free app that lets you compress and unpack any file in a very easy, quick and efficient way.
