.EAR File

The ear file extension is related to Java Enterprise and used for application package units.

The ear is a standard JAR archive, with one or more entries representing the modules of the application, and a metadata directory called META-INF which contains one or more deployment descriptors.

Files with ear file extension can be mostly found as renamed JAR archives with special structure for application modules.

How to open:

Programs that can access or work with JAR files can also work with EAR archives.

How to convert:

It might be possible that programs meant for JAR conversion also support EAR format.
