Many of us use the Windows operating system, without knowing the charms of using other experienced programmers, popular only in narrow circles. However, even the “monster” has a chance to become a role model, as it happened with the Mac operating system, which is based on the amazing kernel of the Linux operating system, named after the famous programmer Linus Torvalds. This article will discuss what a PKG file is, where it is used, why it was created, and how to open it ourselves. This article is recommended for novice users of the Windows operating system, because it is under it that all software will be described.
What is PKG
If an experienced programmer reads this article, then he can proceed immediately to the next paragraph, since the interaction scheme of the operating system components will now be described.
Back in 1980, it was decided to create an object-oriented programming language so that it could be conveniently written on it, but what is objectivity? This is a method in which certain pieces of code are placed in classes, and these classes themselves are connected to other classes and so on. Why is this needed? Imagine that you have a compendium that needs to be rewritten, but the teacher told you that you can use a printer. The choice will be obvious, you do not want to spend a lot of time and rewrite, and order the car to do it.
It is the same in programming, so that, for example, every time you do not write hundreds of lines of code for the button to turn off the program, for this there is its own class that performs this task. You connect it, and everything works.
It is for such a task that a PKG file was created. In Apple's OS X operating system, he plays the role of a controller that checks the installation file for the presence of certain data, because it contains the scripts necessary for installing the application, in short.
In the next paragraph of the article, we will describe in detail how to open this file format on the Windows operating system, because most often it develops applications for Apple technology, no matter how strange it sounds.
How to open a PKG file?
If you are not a programmer, we say right away: you won’t find anything interesting there, only hundreds of lines of automatically filled scripts. However, if you still want to do this, there are some things to keep in mind: the OS X operating system has good enough built-in protection, so if some data does not meet the OS requirements, the file will crash from the execution process.
Instructions on how to open a PKG file on Windows 7:
- First, you must move the file with the PKG extension to any place convenient for you, preferably on the desktop, because access to it is much faster.
- Now you have to download WinRar archiver from the official site - this is the most convenient way to work with this type of file. When installing the application, you can also add associations to other types of archives, so you will have to look less for information on the Internet.
- Drag the archive into WinRar and see the contents of the archive.
- If you want to upload all the files, the “Extract” button will be on top, this button is also available in the context menu if you right-click on the PKG file.
How to make this archive format yourself
As mentioned in the paragraph on how to open a PKG file, this is just a set of automatic instructions. From the word “automatic” you can fully understand that these scripts were not written by a person, but only a compiler of the development environment. If you want to create your own software for the OS X operating system, you will have to do the following:
- Choose a programming language.
- Download the development environment for this programming language, after which it is advisable to read several articles on developing software for Mac, because each OS has its own subtleties.
- Write a program and compile, eventually get a ready-made PKG.
If you have ready-made scripts, feel free to create an empty folder, place them in it, right-click, select “Add to Archive ...” in the context menu, and check the box next to PKG as the format.
How to install PKG files
The files themselves already have all the necessary installation instructions and know their way. OS X operating system with completely closed source code, so it’s impossible to find out exactly where all the files are installed, but this does not prevent them from fully functioning. Do not try to set the installation in manual mode, as this may lead to unforeseen system errors, or the antivirus will “swear” a lot.
Finally
We hope that after reading this article it became clear what a PKG file is, how to use it and why it was created. It is possible that in the future you will become a programmer, so first we recommend reading a couple of dozen articles about the operating system for which you want to develop an application. And only then start writing code, so you can save yourself and users from unnecessary headaches.
