In depth

A closer look at Jar Opener

Jar Opener is a utility with a name that pretty much describes its functionality - it allows you to identify the elements included in a JAR file. Its features are easy to figure out. Since this is a JAR file, there is no installation package available. In other words, you can simply drop Jar Opener on the hard drive and directly run it on any computer that has Java installed. The app's interface is represented by a familiar window with a clean layout. Loading a JAR item into the workspace can be done by using either the file browser or the "drag and drop" functionality.
