What is the purpose of the installer decompression and often a macOSX folder?

As you said, the installation package of ** is a compressed package of files, and the RAR class, it needs to be decompressed into a file to install, so after the installation is completed, it is equivalent to the installation package, and it has nothing to do with the normal operation of the program. Hope!

Some information on the Internet**, after decompression, there will be a folder like "macOSX", which is a file compressed by the compressor using Mac (Mac computer), and it can be deleted without affecting the use at all.

macOS is their development environment, and X stands for the 10th generation of macOS systems. For example, many key figures from leading web framework organizations have chosen Mac as their development platform, and there are also many WordPress plugin and template authors who develop their work on Mac. Compressing a directory on Mac is a very easy task, all you need to do is right-click on the directory and select "Compress to..."Then, the developer can upload this compressed package to the Internet for people**.

But there's a problem, Apple, like other big software companies, is very good at misinterpreting and seconding users, and it doesn't often do exactly what you want. For example, in this case, do you think that the Mac is just adding what you want to the archive? No, Apple compresses the file and writes some "metadata" into it, which is intended to be convenient for other Mac users (just like Windows will add to the ** directory to facilitate the display of preview images).

The files generated by these metadata are "macOSX", which themselves hide attributes on the Mac system, which is indeed convenient for users to operate. But plug-ins, templates and other works are meant to be used by many people, most of them are Windows operating systems, and Windows never likes Apple, macOSX becomes junk files. (The above content** a Sina Weibo is for reference).

In addition to the Windows operating system, there are some other operating systems in this world, such as Linux, such as Mac OS used by Apple computers, and when the files are compressed in the Mac OS X system (*zip), these macOSX files will be generated in the archive. If it comes with a system file, it cannot be deleted; If it is Apple's compressed package, it can be deleted completely if it is unzipped on PC.

In addition to the Windows operating system, there are other operating systems in the world, such as Linux, such as the Mac operating system (*) used by Apple when compressing files in the Mac OS X system, and these Mac OS X files will be generated in the compressed package.

If it is a system file, it cannot be deleted, and if it is an Apple archive, if it is extracted from a personal computer, it can be deleted completely.

The first answer is what it is. The word actually refers to Mac OS X, which is macOS 10, which is an Apple version, analogous to iPhone X, which is the Roman 10.

The second is why. The zip package is packaged in Apple, and you will have this when you unzip it with Windows.

Finally, what to do, this folder is useless, and it won't affect you if you delete it.

This file depends on how it came from, if it is a system file that comes with it (that is, it is in the system disk, it is invisible from the Mac system, and it can be seen from the PC system), it cannot be deleted.

If it's Apple's zip package (..)zip), which is unzipped on the PC, can be deleted completely.
