Editor to share with you what is the difference between 7z and zip. I hope you will gain a lot after reading this article. Let's discuss it together.

Difference: 1, 7z general corresponding software is 7zipzip corresponding to winzip. The compression ratio of 2 and 7z is larger, followed by zip. 3, zip format is relatively common, support is extensive, windows operating system does not install any third-party software can also open zip format; 7z must use decompression software.

Introduction to 7z

The general corresponding software of 7z is 7zip.

7z is a mainstream and efficient compression format with a very high compression ratio. In computer science, 7z is a file format that can use a variety of compression algorithms for data compression. This format was originally implemented and adopted by 7-Zip, but the file format is public, and the 7-Zip software itself is open source under the GNU wide General Public license (GNU LGPL) agreement. The latest version of the LZMA SDK is V9.34. The MIME type of 7z format is application/x-7z-compressed.

Generally speaking, the 7z format of 7-Zip can be 30-70% smaller than the compressed file using zip format.

And the zip format created using 7-Zip is 2-10% smaller than that created by most other compression software.

Main features:

Open source and modular component architecture (allows the use of any compression, conversion, or encryption algorithm)

Highest compression ratio

Powerful AES-256 encryption

Algorithms that can be changed and configured for compression

Support for very large files (up to 16EB)

Unicode filename support

Support solid compression, allowing files of inner classes to be compressed in a stream, so that similar content can be effectively compressed

Supports header compression of files

Support for multithreaded compression

The 7z format supports 256-bit key AES algorithm encryption. The key is obtained by the SHA-256hash algorithm of the secret code provided by the user (using a large number of iterations to make the brute force decoding of the secret code more difficult)

Introduction to zip

The ZIP file format is a file format for data compression and document storage, formerly known as Deflate, invented by Phil Katz, who published the data in this format in January 1989.

ZIP usually uses the suffix ".zip" and its MIME format is application/zip. Currently, the ZIP format is one of several mainstream compression formats, and its competitors include the RAR format and the open source 7z format. In terms of performance, the compression ratio of RAR and 7z format is higher than that of ZIP format, while 7-Zip is gradually used in more fields because it provides free compression tools.

Microsoft has built-in support for zip format from the Windows ME operating system, and can open and make compressed files in zip format even if the user's computer does not have decompression software installed. OS X and the popular Linux operating system also provide similar support for zip format. Therefore, if you spread and distribute files on the network, the zip format is often the most common choice.

The difference between compressed file 7z and zip is:

1, 7z generally corresponds to 7zipzip corresponding to winzip.

The compression ratio of 2 and 7z is larger, followed by zip.

3. Zip format is more common and extensive. Windows operating system can open zip format without any third-party software. 7z you must use decompression software.

After reading this article, I believe you have a certain understanding of the difference between 7z and zip. Want to know more about it. Welcome to follow the industry information channel. Thank you for your reading!
