The command-line versions of 7Zip look to the directory where the 7Zip executable file is located to find the files you are managing. For example: 7z a -t7z Encrypt.7z Test8.txt -mx=7 -mhe=on uses the Parameter and Switch Syntax: Use a separate -m switch for each parameter when adding them to the command line. "command" "switches" "full_path_archive_name" "full_path_file_name"Įg 7z a -p 7Zip_Archive Test_file.txt creates a 7z formatted archive named 7Zip_Archive that is protected with a password, then adds a file named test_file.txt to the archive. " 7za" for 7Zip for Windows ( 7za.exe) users The general command line syntax begins by invoking the version of 7Zip you are using: Please change the invocation to " 7za" when applying these examples for use in 7-Zip for Windows. NOTE TO WINDOWS USERS: the following syntax examples begin by invoking the Linux command-line version, "7z". Other than this program invocation command, all commands, parameters and switches are identical for all command-line versions. Invoke the version of 7Zip you are using by entering " 7z" for P7Zip (7z.exe), or " 7za" for 7Zip for Windows (7za.exe) to start either the P7-Zip or 7za application prior to entering commands. To begin a session, open a terminal window. Windows users who want to use the command-line version should generate a Help Desk ticket to install the standalone 7za.exe version. Although its interface is deceptively simple, the command-line versions of 7ZIP are highly customizable archiving programs when used with the command parameters and switchesdescribed below. ![]() See also: File Archiving and Compression, Accessing and Sharing Files, Network Access, Windows Terminal Servers 7-Zip Versionsħ-Zip is an Archive and File Management utility available in command-line versions for Linux/Mac, "P7Zip" (7z.exe), as well as for Windows, "7za" (7za.exe).

If there are similar files in different folders, the sorting “by type” can provide better compression ratio in some cases. You can get big difference in compression ratio for different sorting methods, if dictionary size is smaller than total size of files.
