T3rM1nat0Rr3 Posted February 7, 2020 Share Posted February 7, 2020 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 Astron for the update. Download Link to comment Share on other sites More sharing options...

keyman Posted February 9, 2020 Share Posted February 9, 2020 What's new after 7-Zip 19.02 alpha: 7-Zip now supports new optional match finders for LZMA/LZMA2 compression: bt5 and hc5, that can work faster than bt4 and hc4 match finders for the data with big redundancy. The compression ratio was improved for Fast and Fastest compression levels with the following default settings: Fastest level (-mx1) : hc5 match finder with 256 KB dictionary. Fast level (-mx3) : hc5 match finder with 4 MB dictionary. Minor speed optimizations in multithreaded LZMA/LZMA2 compression for Normal/Maximum/Ultra compression levels. bzip2 decoding code was updated to support bzip2 archives, created by lbzip2 program. Some bugs were fixed. New localization: Turkmen. Link to comment Share on other sites More sharing options...
