Starting with version 4.0, the WinZip Command Line Add-On can be used to unzip any of the archive types that are supported by WinZip. Additionally, version 4.0 can create LHA files. For simple archive types, you would use the same type of unzip command that would be used with Zip files.

P7zip is the command line version of 7-Zip for Unix/Linux, made by an independent developer It is distributed as Linux binaries and in source code form on Sourceforge. Download the source code, and run make in the folder you extract the archive to. However, most Mac users do not actually know what this is. Actually, a.7z file is an archive format the stand for 7-zip and you can compare it to any other archive that you have on your Mac. However, by default, your Mac does not know how to handle these kinds of files. That is why most Mac users would ask on how to open.7z files on Mac.

What is a tar file?

A tar file is an archive file created with a software utility of the same name. Compatible with Unix, Unix-like and Microsoft Windows, it is used to collect multiple files into an archive file (which can be called a tarball). The name tar stands for tape archive, and the format was originally developed to save data to tape drives.

It is just a way of collecting data of all kinds (files, directories, etc.) together and doesn’t do any kind of compression. A basic tar file has a .tar extension. You may see files ending with .tar.gz or .tar.bz2. What are they? They are still tar files (or tarballs). In cases like these, files are not only packed but also compressed with compressors such as gzip or bzip2. By doing so, one can create a smaller tar file for more efficient backup or distribution.

7z is a compressed archive file format that supports several different data compression, encryption and pre-processing algorithms. The 7z format initially appeared as implemented by the 7-Zip archiver.

The 7z format provides the following main features:

Unzip 7z Mac Command Liner

  • Open, modular architecture which allows any compression, conversion, or encryption method to be stacked.
  • High compression ratios (depending on the compression method used)
  • Rijndael/AES-256 encryption.
  • Large file support (up to approximately 16 exbibytes).
  • Unicode file names
  • Support for solid compression, where multiple files of like type are compressed within a single stream, in order to exploit the combined redundancy inherent in similar files.
  • Compression and encryption of archive headers.
  • Support for multi-part archives : e.g. xxx.7z.001, xxx.7z.002, ... (see the context menu items Split File... to create them and Combine Files... to re-assemble an archive from a set of multi-part component files)

The format's open architecture allows additional future compression methods to be added to the standard.

While 7z compression uses the LZMA method by default, the 7z format also supports the PPMD, BCJ, BCJ2, BZip2, and Deflate compression methods.

The 7z format supports encryption with the AES algorithm with a 256-bit key. The key is generated from a user-supplied passphrase using an algorithm based on the SHA-256 hash function.
