0 Zanaffer Posted May 13, 2011 Share Posted May 13, 2011 I am very fond of 7zip. It's free, and open source. This means that it's rather unlikely that you'll ever run into a situation where you cannot decompress your files (unlike, say, the more or less extinct proprietary stuffit archives on the Mac platform).

0 huddy Posted May 13, 2011 Share Posted May 13, 2011 I'd recommend WinRAR. Link to comment Share on other sites More sharing options...
0 ajua Posted May 13, 2011 Share Posted May 13, 2011 For a free alternative and better compression, 7-Zip is the best. WinRAR on the other hand does a very good at compressing (not as much as 7z, but very close) and its main advantage is a more polished interface and richer features. If you want to go the 7-Zip way, I can suggest you download an MSI installer I make for 7-Zip (among other free applications) which is customized with better looking icons, configured to compress as much as possible and also included is a little application called 7z SFX Extractor which can extract .7z archives out of self-extracting exe files. By default it doesn't associate itself with the supported formats (I use WinRAR most of the time) but you can associate the file you want in the options menu. Links are on my signature.

0 +BudMan MVC Posted May 13, 2011 MVC Share Posted May 13, 2011 I also use izarc, but how would it do better 7z compression? - when it uses the 7z dll to do the compressions with.. Its just a different UI that uses a bunch of different compression tools Anyone can use the 7z libraries in their programs -- thats what open source means.. I don't see how it would be possible to get better compression with some tool using the library of the software, vs the original software using the library ;) http://www.7-zip.org/faq.html How can I add support for 7z archives to my application? One way is to use the 7z.dll or 7za.dll (available from sf.net for download). The 7za.dll works via COM interfaces. It, however, doesn't use standard COM interfaces for creating objects. You can find a small example in "CPP\7zip\UI\Client7z" folder in the source code. A full example is 7-Zip itself, since 7-Zip works via this dll also. There are other applications that use 7za.dll such as WinRAR, PowerArchiver and others. The other way is to call the command line version: 7za.exe.

0 Fred Derf Veteran Posted May 13, 2011 Veteran Share Posted May 13, 2011 Compression software is only a useful tool if the person expanding the archive has the software and the technical inclination to do so. When dealing with "real people", I stick to using .ZIP (which can still be done with WinRAR and other programs). For my own use then it doesn't particularly matter. Getting an extra 10% compression isn't really that big a deal to me. Carbon Fiber 1 Share Link to comment Share on other sites More sharing options...

Getting an extra 10% compression isn't really that big a deal to me. I'm pretty much the same as this. However there are times when there is a drastic difference between 7zip/WinRAR and zip style utilities. Usually for me it's when it comes to archiving many similar copies of a particular directory (like from a backup script that copies a particular directory every day/week). I recompressed a set of weekly backups (approximately 150 consecutive weeks worth) a few weeks ago which came to a total of 4.3 million files taking up 22 GB. The tar.gz file (which is in the same league as zip) was 9.05 GB. The 7z file was 85 MB! Link to comment Share on other sites More sharing options...
0 firewire1290 Posted May 14, 2011 Author Share Posted May 14, 2011 first off all thanks for letting me know what open source means and showing me how izarc uses same dll file of 7zip.but for some strange results izarc show little bit more compression. I also use izarc, but how would it do better 7z compression? - when it uses the 7z dll to do the compressions with..

0 Gocom Posted May 14, 2011 Share Posted May 14, 2011 but for some strange results izarc show little bit more compression. Same compression algorithm will always give (relatively, excluding optional preferences) same results. Otherwise it wouldn't produce compliant compression, and decompressing the package wouldn't be possible. If it gives different results, you are using different algorithm or feeding it with a different compression level or an optional compression mode.

0 Ulpian Posted May 14, 2011 Share Posted May 14, 2011 WinRAR costs money. After 40d of usage it need to be registered, w/o this it is considered pirated software. It works w/o crack, but it is non-licensed ! 7-ZIP - it is free. Link to comment Share on other sites More sharing options...
0 Gerowen Posted May 14, 2011 Share Posted May 14, 2011 I just took a folder full of my photos and compressed it into various archive formats using file-roller. Here's my results: Uncompressed Size: 299.4 MB .tar.gz Tarball: 296.8 MB .tar.bz2 Tarball: 295.1 MB .zip: 297 MB .7z: 297.2 MB .rar: 297.3 MB So out of all the ones I tried, the tar.bz2 tarball offered the best compression.

One could argue that the "best" archive format from that list would then be .ZIP considering the benefits of greater compatibility and given that the compression doesn't seem to matter (in that example). I'm certainly not going to do a dance over 1.9MB of increased compression. That isn't even 1%. Link to comment Share on other sites More sharing options...

It depends on what you're trying to compress. Photos are already compressed, and trying to compress them even more isn't going to save much space. ZIP is fine in most cases, but if you're compressing a bunch of similar files, 7-zip will get much better compression because it creates solid archives.

0 lalalawawawa Posted May 16, 2011 Share Posted May 16, 2011 Yes i agree with you.i use the same as many people are not aware of such tool so there's Default Windows Compression which can extract files from .zip extension. Only one problem, however. It cannot extract files with UTF names. Meaning it would extract "lala.txt", but not "????.txt". Link to comment Share on other sites More sharing options...

0 epk Posted May 22, 2011 Share Posted May 22, 2011 Winrar is paid, but the license isn't so expensive. It's also lifetime and you can install it on all your computers. I like it cos it's pretty fast and stable. IceDogg 1 Share Link to comment Share on other sites More sharing options...
0 farmeunit Posted May 22, 2011 Share Posted May 22, 2011 I use WinRAR because GMail doesn't scan RAR files for filetypes. I know it scans ZIP and 7z, and I store and send lots of .bat files and .exe to other people. For general use, I use iZarc. nXqd 1 Share Link to comment Share on other sites More sharing options...
