Question: What is an JAR File?

Have you found, downloaded or received an JAR file, but don't know which software program is required to open it?

Before attempting to open an JAR file, you'll need to determine what kind of file you are dealing with and whether it is even possible to open or view the file format.

Answer: Files which are given the .JAR extension are known as Java Archive files, however other file types may also use this extension. If you are aware of any additional file formats that use the JAR extension, please let us know.

How to open a JAR file:

The best way to open an JAR executable file is to simply double-click it and let the default assoisated application open the file. If you are unable to open the file this way, it may be because you do not have the correct application associated with the extension to view or edit the JAR file.

This executable file format was added to our database by a visitor to this site, but no additional information was provided. We have yet to investigate this file type further, or there was not enough information available at the time to report accurately on the format.

Please check back soon for more information as we are constantly updating our file descriptions based on search frequency.

Tip: Try to open the JAR file using a text-editor such as Notepad, as many file types contain simply contain unformatted plain-text and can viewed correctly using this method.

This is used in 2 ways: as an executable java program, or as an archive file. Most archiving programs can be used to open this file.
