jar files are basically zip files with an extension of jar. If you just want to view the contents of the file, you may use programmes like winzip or winrar etc.

A jar file is essentially just a structured ZIP file. You can view the contents easily by temporarily changing the extension from .jar to .zip, and then using any compression utility to extract and view the contents. Don't forget to change the extension back to .jar when you are done! A side note, it is not recommended to make changes to jar files in this manner - the compression utilities do not correctly compress the files in every case, and they do not always include the manifest file required for it to work. If you want to change the contents, you are better off rebuilding the jar file from within an IDE.

It will give you this option because you might have two or more programs on your computer that can open this file. For example, a Java JAR file could be open with either Java Runtime Environment or in an archiving program such as WINRar. It lets you choose what program to open that file with. Say the JAR file was a game, you would use the runtime environment to play it and WinRar to mod it.
