RAR, the best if you don't care about licenses In other words, the 7z can present more problems than other formats such as ZIP. On the other hand, as I mentioned, compression failed me using Ark, so I personally have that thorn in the side and I can't quite trust him. The main reason for using the 7z is its high compression level, but it is not worth it if we are going to compress large files while we work because we are going to waste a lot of time / resources of our equipment. Supported compression algorithms (LZMA / LZMA2, PPMd, BZip2) can benefit from parallel computing on modern multi-core CPUs. It was introduced in Windows as 7-Zip and ported by the p7zip team to Unix platforms. It offers AES encryption and a high level of compression, one of the best, most cases higher than RAR or ZIPX. The 7z is a modern compression format and open source. It can be used as a substitute for ZIP and, as in the case of ZIPX, for a licensing issue, this being totally free. ZIP format), a combination of Lempel-Ziv (LZ77) encoding and Huffman encoding. Compression is based on the DEFLATE algorithm (also used as the default algorithm in the PKZip / WinZip. The GZ extension designates a single file compression format, created for the GZip project (GNU Zip or "free Zip"), started in 1992 by Jean-Loup Gailly and Mark Adler in order to provide a free replacement for compression solutions. Many of the files we download for Linux are in the tar.gz format. S only provides archiving (concatenate input data and metadata into a single output file), delegating functions like compression, encryption, parity / integrity check to external software that works in the pipeline with TAR command output. This is TAR and we mention it because it is used a lot in Linux. Īs we explained earlier, we were going to mention a compression format that did not compress. I would recommend using ZIPX only when you don't want to use RAR, that is, for an economic and licensing issue. The problem is that when using ZIPX we lose the strengths of ZIP: the computer consumes more resources and compression / decompression is slower. It is the ZIPX and among its possibilities we have that it compresses more than the ZIP, something comparable to the RAR format. If we have talked about the ZIP, we have to talk about an evolution of the same. Other formats, although available, can present problems in some operating system, and this is something that has happened to me when compressing files in 7z in various places since Ark. The reasons for choosing ZIP as the compression format are the speed and it works perfectly on any operating system. The latest versions introduced AES encryption.The ZIP format is available on virtually any operating system, such as Linux or even much more closed systems such as Apple's iOS. It is based on Deflate Lossless compression, which makes it ideal for archiving large amounts of combined data, such as a backup. Compression in ZIP is very fast and does not require many resources, at least if we compare it with compression in 7z or RAR.Being one of the first, it has been overtaken over time by other formats such as 7z or RAR, but it still has its strengths: Most popular compression formats ZIP, fast and lightĪs we have already mentioned, ZIP is a very famous compression format, partly because it is "The one of all the life" in Microsoft systems. 2 Of these compression formats, which is the best?.1.6 RAR, the best if you don't care about licenses.
