jalaffa Posted April 1, 2015 Share Posted April 1, 2015 7-Zip is an open-source file archiver, that offers the highest compression ratio, using the new 7z format, which delivers compression results that are usually 30-50% better than standard ZIP. We tested it with a server log file, which compressed with ZIP had a file size of 18 mb and using 7-Zip was reduced to 8 Mb (results may vary, depending on file type). 7Zip supports 7z, ZIP, CAB, RAR, ARJ, GZIP, BZIP2, TAR, CPIO, RPM and DEB formats, so it can be used with all popular archive files. The program offers a basic file explorer interface and also integrates into the Windows right-click menu. It can be associated with any of the supported formats and also offers command/line support.Thanks to jasonliul for the update.Download Link to comment Share on other sites More sharing options...

Fallon Posted April 2, 2015 Share Posted April 2, 2015 Still no RAR5 support. :(And that's what he promised. The second.jpg start up bug in Archives is greeting again too. But count your blessings. It's great that Igor is still at it. Link to comment Share on other sites More sharing options...

Fallon Posted April 19, 2015 Share Posted April 19, 2015 7-Zip will remember the settings that were last used when making an Archive.------------Important stuff can be Archived with a 'Non-solid' setting. It's safest.If such an Archive gets corrupted later in time, you can possibly extract parts.For sharing, a 'Solid' Archive setting is okay. These Archives put things in the same stream. Result is better compression, and no recovery when the Archive gets corrupted.A low Solid Block size means fast decompression. A large Dictionary size will improve compression a little bit more, at the expense of using extra Memory (also to unpack). Link to comment Share on other sites More sharing options...
jamesbond Posted April 19, 2015 Share Posted April 19, 2015 non-solid compression usually gives a lot worse ratio. solid mode is quite common since years, honestly.a lot of unix archives, such as .tgz or .tar.bz2 are solid too. Link to comment Share on other sites More sharing options...

And for any Archive you like to preserve long-term.Nowadays many things are already compressed in advance (exe-compressors, other specialized compression).This makes the difference between 'solid' and 'non-solid' small in many cases.For the masses Windows compression is the issue.Solid starts to matter when many different filetypes are compressed.Example: the 'VLC distribution 7z' Archive.For that package settings are used that give a lesser result than with the settings mentioned here. :) Link to comment Share on other sites More sharing options...
