Creates the common ones
7z, ZIP, TAR, GZip, BZip2, XZ and Apple Archive, with split volumes, AES-256 encryption and self-extracting archives.
Lives in Finder
A context menu to compress, extract, test and checksum; Quick Look previews of archive contents; thumbnails with the file count.
Two-pane file manager
Browse folders and archives side by side; copy and move between them with F5 and F6, like the Windows 7-Zip you know.
Full compression control
Level, method, dictionary, word size, solid blocks, threads, update modes — with a live memory estimate.
Speaks your language
English, Russian and Tajik in full, plus menus and dialogs in 87 more languages from the 7-Zip translations.
