How to open file with JAR extension?

JAR file description

Sun Microsystems originally developed the .JAR file extension. The files that are with the .JAR extension are basically the compressed files that make use of ZIP format to compress the required Java files.

Such files with the .JAR format consist of Java metadata and classes. Programs like SeaMonkey, Firefox and Thunderbird make use of the .JAR files to store program themes and application add-ons. Moreover, .JAR files can be used to store files, in the same manner as the ZIP files do. These files can hold on to multiple files compressed in one folder or a large file compressed to achieve a manageable file size.

We hope we helped you solve the problem with the JAR file. If you do not know where you can download the application from our list, click on the link (which is the name of the program) - you will find more information there on the location where to download the secure setup version of the required application.
What else may cause problems?
There can be more reasons which determine that you are not able to open the JAR file (apart from the lack of the proper application installed).
First - the JAR file may be incorrectly linked (associated) with the application installed to support it. In this case, you need to change this link by yourself. To do this, right-click on the JAR file # that you want to edit, click "Open with" and then select the program from the list that you have installed. After this operation, the problems with opening the JAR file should be solved forever.
Second - the file you want to open can simply be damaged. Then, the best solution is to find a new version, or download it again from the same source as before (maybe for some reason in the previous session the download of the JAR file has not been completed and it cannot be opened properly).
