Jordan de Souza Posted July 19, 2011 Share Posted July 19, 2011 I wish to know what format have the better compression ratio [latest software] and the better unpack ratio!Feel free to tell me other format that is faster.Also software recommendations are welcome.

OhMyGod Posted July 19, 2011 Share Posted July 19, 2011 Take a look at this benchmark from PeaZip and decide for yourself.I have read other benchmarks for compression tools and PeaZip always comes out on top when you consider the compression ratio and speed together. Thanks. :D Link to comment Share on other sites More sharing options...

Thanks. :DThank you for your reply.Also i have been reading a lot of information on this website: http://www.maximumcompression.com/index.htmlthere is a intriguing "faq" on the lower section of this page: http://www.maximumcompression.com/data/summary_sf.phpSo for everyday users, like me, they recommend 7zip or Winrar.I have being reading a bit of the ARC format... maybe if the new groups start releasing in this format it became popular... seems overall greater than rar and 7z format.

HX1 Posted July 19, 2011 Share Posted July 19, 2011 WinRAR is usually the everyday choice.. Now its is sort of split and can depend on your system as for which one you prefer.. Some would say 7zip actually has better compression for some files types while WinRAR has better on others... When it comes to decompressing.. some users with different ( older ) chips state they have better performance out of WinRAR... while 7zip will take longer and not show much more compression for the loss in time and resource usage for decompression.... WinRAR IMO.. is a good balance between the two but if I am looking for security I go with PGP Desktop ... Thought I still do use the options in WinRAR..There are other formats and methods of using compression and decompression as well as other format available.. Some can depend upon the hardware and tech that it is being performed on due to the computations and other aspects as I understand it..safety is a consideration for some which also alters that decision... while it may not seem relative to offering the best choice.. it is a consideration of options and available functions.. While some may see operable aspects a favorable plus over another..it may not offer the level of encryption nor protection that another might...and thus the decision is made for other reasons...Really just asking which one is not really a straight forward question where it may seem as much.. to those who use it for simplicity sake on a daily basis.. it may seem as much...or only uses it to access files online or from downloads...

Arc is better overall when multiple types of files are in game. Link to comment Share on other sites More sharing options...
Administrator DKT27 Posted July 19, 2011 Administrator Share Posted July 19, 2011 When comparing both WinRAR and 7-Zip. 7-Zip, in most cases will give you better compression. Also, 7-Zip properly utilizes all my cores to compress/extract. WinRAR on the other hand, inspite of enabling all the cores/multi-core thing, takes ages to do the same. But, none the less, .rar is a standard format in scene.If you really want higher compression, try something like KGB Archiver, may take days to compress/decompress, but worth it. ;) Link to comment Share on other sites More sharing options...
HX1 Posted July 19, 2011 Share Posted July 19, 2011 Yeah I remember Marik talking about KGB a long time ago... Wonder what it would be like on good board with dual processors? :think: Link to comment Share on other sites More sharing options...
AlienForce1 Posted July 19, 2011 Share Posted July 19, 2011 If you want high compression rate - take a look at Uwe Herklotz`s uharc , download hereBased on the original uharc , Sam Gleske developed a free version (UHARC CMD) that integrates in Windows shell , download here Link to comment Share on other sites More sharing options...

I used a mixed of photoshop/png images, and the program files folder to test. Run on Windows 7 64-bit. Result: 7Zip had the best compression, but winrar was almost as good and much faster. Winzip fell behind in all areas. Built-in zip was fairly fast but didn’t offer good compression.

Nima Posted July 19, 2011 Share Posted July 19, 2011 I myself prefer RAR and WinRAR; and suggest you this for like other says, everyday use.It's very light and stable and compress/decompress almost all archive formats and it's very popular too.

Jordan de Souza Posted July 19, 2011 Author Share Posted July 19, 2011 Thank you for all your replies... after taking a deeper look for a everyday user like me, i think the best solution in program terms would be Peazip since it uses both freearc 0.666 and 7 zip compression methods all in one software with the winrar interface and speedier decompression compared to winrar. So... For now, i'd using peazip for decompress and kgb for compressing, problem with kgb is that it takes like a life to goes true. But final results may worth in some cases.

Jota.Ce Posted July 19, 2011 Share Posted July 19, 2011 7-Zip is slow as hell when you want to gain extra bytes.WinRAR for me. I prefer faster methods, and i even use WinRAR ZIP compression in big files. Link to comment Share on other sites More sharing options...

myidisbb Posted July 20, 2011 Share Posted July 20, 2011 winrar won the war period. back in the late 90's you had to have rar, winrar, ace, winace, arc etc. its so much better having one that will open everything and is friendly. Link to comment Share on other sites More sharing options...
Jordan de Souza Posted July 20, 2011 Author Share Posted July 20, 2011 Thank you for your replies... Well... I'm a winrar user since the day i started needing decompressing software, back in the 90's but I'm also an enthusiast I wish you guys give a try on the peazip... the only thing i dont find out was the "view" feature on the winrar, other than that is heavily user friendly.
