Where is the advantage of RAR compared to 7Z 20

I think the main reason is that WinRAR is older than 7-zip qualifications, and its position in the minds of software users is deeply entrenched, and another influencing factor is that it is better to charge than to pay for it.

The reason why WinRAR has such an unshakable position is that ten years ago, when WinZip still dominated the compression software, but the launch of WinRAR, relying on the advantage of supporting both Zip format and RAR format, gradually replaced WinZip's position, because WinRAR does not need to install WinZip anymore. One of the main reasons for the decline of Winzip is that it does not support the RAR compression format.

I think that if the 7-zip archive format becomes the mainstream compression format in the future, then 7-zip may replace winrar

RAR, compression, exe, etc., have a higher compression ratio.

7Z compressed text** has a relatively high compression ratio, especially BMP can reach 10%, 7Z requires extremely high memory support and time, and RAR is relatively small.

It depends on what you like, and I like to use whichever I like, and I like to use 7z, because it's small, and I'm not afraid of wasting time.

zip is currently the oldest compressed file format, as for the advantages, I think it is that all aspects of the motivation are very balanced, and there will not be too slow and too large a compression rate.

RAR is relatively new compared to ZIP, and the compression ratio is higher than ZIP, but the disadvantage is that compression is more time-consuming.

As for ISO, it's hard to say the advantages, the only thing is that it can play the role of an optical drive. But its role is still very large, and now the files used to install the system and large software such as office are compressed and installed with it.

7z is a format that has emerged in recent years, and its advantages are high compression ratio, fast decompression, and fast compression. The downside is that it is very slow to compress or decompress some things.

As for the difference, it seems that in addition to the difference in suffix, only ISO can burn virtual optical drives.

I only know that ISO is the format dropout of the system installation package, and the rest is the dropout of the normal file compression package.

zip is a kind of standardized and open compressed file, the algorithm is uncertain, but it is mainly used deflate;

7zip is similar to zip, the algorithm is uncertain, mainly using bzip2 and lzma, and it is completely open source;

zip and 7z are more like compression containers, as the algorithm is not formatted fixed, allowing support for other compression algorithms).

TAR is a common type of archive file in Linux (it does not natively include compression);

Size & Difference.

The tar is uncompressed, with a higher efficiency than compression, followed by a zip, followed by 7z.

Advantages and disadvantagesIn Linux, tar is generally used in combination with other compression algorithm files without file management, using tar to package the entire file directory structure into a file, and then using gz, bzip and other compression algorithms to compress it into a single time. It is also a common processing method for compressed archives in Linux.

zip is relatively old, and the format specification can be known, so it has accumulated a variety of add-and-decompress implementations, and has good compatibility, but the existing file formats are relatively backward, and there will be garbled file names (because the file names are encoded in non-unicode).

7z is newer, the compression efficiency of the algorithm used is much better, the compatibility is not as good as zip, 7z's files and management programs are open source, the file format is also better (support unicode file names), the performance of the two main compression algorithms is very good, it's just that when it can be popularized and replace zip.

Finally, many domestic compression software supports these algorithms, 2345 good pressure, 360 compression.
