How to purge unused source/class files from Directory tree
<p>We have about 280 Java source code spread over 10 packages, and a bunch of txt and image files for a software project. Quite a few of them are not being used currently. They do not break the system, since we can just do a "javac <em>/</em>/*.java" and "jar cmf metafile " to build up the executable jar which works. The question:</p>

<p>How do we find the class files never accessed, or image/txt files never used as resources in the jar?</p>
