File extension .JAR
The JAR (Java Archive) file extension is associated with the Java Runtime Environment (JRE). It is a platform independent file format used to combine multiple class files and associated metadata time into one file for distribution. JAR files are not dependent on any specific hardware or operating system, and can be used in any Java environment. It works like a ZIP file, by compressing more than one files into a single unit for easier management and storage.
Technical Details
A JAR file is based on the popular ZIP format, and can be created with applications like WinZip, WinRAR, or 7-zip. It is slightly different though, as it contains the specific data needed by the Java Runtime. The manifest file within a JAR contains attribute/value pairs which contain certain settings that can influence the behavior of a Java application when it runs. Typically, the manifest will include the version of Java used to create the JAR and its name, along with other information.

After installing the required software, the operating system will usually automatically associate an unknown file type (in this case .JAR) with the new application. If this does not happen, we can help the system a bit by selecting the software for it, which it should always use to open files with the .JAR extension.
When choosing the software we can select the system to use this software every time.
Remember!
Using it for the first time it is good to check whether the .JAR file opened in the application can be read by us and opens in a way that allows us to use it. If everything is in order, select this option the next time you open a file with the .JAR extension. However, if the file has not opened correctly, we have to look for a different software, with which we can open files with the .JAR extension. Select a different software from our list and install it on your computer. After the software is installed, repeat inspection openings of a .JAR file. Sometimes you have to repeat the operation several times.
Other instructions
If none of the programs listed by us to work with the .JAR file has not meet your expectations, you can try searching other websites. But remember to avoid downloading programs "that can open any file". These applications not only have very limited functionality, but may also expose you to expense tens of dollars when purchasing a license.
In the vast majority of cases you will find the program dedicated to support the .JAR file, or any other file format. In addition, there is a chance that it will be a free program, and its functionality (concerning the .JAR file) will be extended to the maximum.
It is also good to check
- if the .JAR file has no errors
- or if it has been copied (or downloaded by the browser) thoroughly
