.classpath is hidden, which doesn't allow me to add any jar files
<p>I have downloaded a sample in Samsung BLE SDK, but the .classpath file is hidden in the sample folder and i can't add any jar files in this project because of that. I always get this error:</p>

<p>"could not write file in .classpath" </p>

<p>How can i make this .classpath file visible?</p>
