Update Server for extension type="file"

Question

I've developed a "file" extension that works just fine, but trying to publish it in JED I need to setup the update server entry, but I really don't know how to setup that for my new extension, which is of type "file".

<?xml version="1.0" encoding="utf-8"?>
<extension type="file" version="2.5" method="upgrade">
...
...

I have setup a lot of update servers for my other extensions which are plugins, but never setup for "files". So far my update server manifest look like this:

<?xml version="1.0" encoding="UTF-8"?>
<updates>
   <update>
      <name>My Extension Name</name>
      <description>Description by me</description>
       <element>Don't know if this is needed</element>
      <type>file</type>
      <folder>Whats should I put in here?</folder>
      <client>0</client>
      <version>1.0.0</version>
