Question

How do I go from jar:file:/C:/Program%20Files/test.jar!/foo/bar to a File that points to C:/Program Files/test.jar?

Answer 1

The following code works for me (based on How do I get just the jar URL from a jar: URL containing a "!" and a specific file in the jar?):

URL url = new URL("jar:file:/C:/Program%20Files/test.jar!/foo/bar");
JarURLConnection connection = (JarURLConnection) url.openConnection();
File file = new File(connection.getJarFileURL().toURI())
