The Unarchiver is an absolutely free macOS app that can be successfully used as a substitute for Apple's BOMArchiveHelper.app, the free built-in unarchive utility. At the moment, The Unarchiver is distributed directly on the developer’s website and through Apple’s Mac App Store, the single difference.

ZIP is an archive file format that supports lossless data compression. A ZIP file may contain one or more files or folders that may have been compressed. The ZIP file format permits a number of compression algorithms. The format was originally created in 1989 by Phil Katz, and was first implemented in PKWARE, Inc.'s PKZIP utility, as a replacement for the previous ARC compression format by Thom Henderson. The ZIP format is now supported by many software utilities other than PKZIP. Microsoft has included built-in ZIP support (under the name 'compressed folders') in versions of Microsoft Windows since 1998. Apple has included built-in ZIP support in Mac OS X 10.3 (via BOMArchiveHelper, now Archive Utility) and later. Most free operating systems have built in support for ZIP in similar manners to Windows and Mac OS X.

ZIP files generally use the file extensions '.zip' or '.ZIP' and the MIME media type application/zip. ZIP is used as a base file format by many programs, usually under a different name. When navigating a file system via a user interface, graphical icons representing ZIP files often appear as a document or other object prominently featuring a zipper.

ZIP is one of the most widely used compressed file formats. It is universally used to aggregate, compress, and encrypt files into a single interoperable container. No specific use or application need is defined by this format and no specific implementation guidance is provided. This document provides details on the storage format for creating ZIP files. Information is provided on the records and fields that describe what a ZIP file is.

Open/Extract ZIP File on Linux

You need to install unzip. unzip lists, tests, or extracts files from a ZIP archive. The default behavior (with no options) is to extract into the current directory (and subdirectories below it) all files from the specified ZIP archive. A companion program, zip, creates ZIP archives; both programs are compatible with archives created by PKWARE's PKZIP and PKUNZIP, but in many cases the program options or default behaviors differ.

Install unzip on CentOS and Fedora

# yum install unzip

Install unzip on Debian and Ubuntu

$ sudo apt-get install unzip

Extract a ZIP file on Linux

$ unzip sample.zip

Extract to a particular destination directory, you can use:

$ unzip sample.zip -d <destination_directory>

You can install SecureZIP from the Windows command-line prompt or a batch file. In the command line, you can set values for various properties to customize the installation.

The command line looks like this:

where:

/S is a switch that tells InstallShield^® to run silently and not to display various initial screens (that say, for example, Preparing to install )
/v is a switch that must be used to pass any specified SecureZIP properties to the Windows installer.
<properties> is a list of property settings

You can also optionally pass in a switch to specify either the Basic UI, that displays a dialog containing only a Cancel button to allow canceling of the installation; or No UI, that displays no dialog. Both Basic UI and No UI can run unattended. The default is the full, graphical UI, which is interactive and so cannot run unattended.

File Type	Property
ZIP	PKZIPASSOC
UUEncode/XXencoded	PKUUEASSOC
GZIP and TAR	PKGZASSOC
BZIP2	PKBZ2ASSOC

If you do not want a particular file type associated with SecureZIP, set its corresponding property to 0 in the command line. For example:

<name of pkzip installation file> /S /v'PKCABASSOC=0'

By default, the installation creates shortcuts to SecureZIP. If you do not want a shortcut created in one of the places listed in the table below, set the corresponding property to 0.

SecureZIP Attachments, the extension module for zipping email messages and attachments, installs by default if Outlook is detected. To not install SecureZIP Attachments, set the PK_PKZIP_ATT property to No using a command line like this:

If you want SecureZIP to install somewhere other than the system's Program Files directory, use the INSTALLDIR property and set it to the new location. For example:
The SaveSecure feature adds to Miscellaneous options an Office Integration page that contains options to automatically open an archived file in the file's associated application program, and to enable Office Integration.
The SaveSecure Office Integration option adds menu commands and toolbar buttons to some Microsoft Office applications to make it possible to open documents of appropriate types in the application directly from ZIP files. Documents can also be saved directly to ZIP files using these commands.
To not install the SaveSecure functionality, set the SAVESECURE property to 0:
<name of pkzip installation file> /S /v'SAVESECURE=0'
