Where are IntelliJ scratch files located?

In IntelliJ IDEA 14, we can create scratch files from Tools > New Scratch File...

Are they stored in some temporary files? If the answer is yes, where are they?

Attempts:

1) I pressed right click > Copy Reference and I pasted it:

1d0b26a2/scratch.2:1

2) I opened .idea\workspace.xml and I have the following part for scratch files:

  <file leaf-file-name="scratch.2" pinned="false" current-in-tab="true">
    <entry file="scratchpad://1d0b26a2/scratch.2">
      <provider selected="true" editor-type-id="text-editor">
        <state vertical-scroll-proportion="0.0" vertical-offset="0" max-vertical-offset="636">
          <caret line="0" column="0" selection-start-line="0" selection-start-column="0" selection-end-line="0" selection-end-column="20" />
          <folding />
        </state>
      </provider>
    </entry>
  </file>

For a normal file the entry path starts with file:// instead of scratchpad://.

I upgraded my IntelliJ IDEA to 14.1 and I found the scratch files.

If you create a scratch file, its path can be found in many different ways:

1. On the title bar

2. Right click on the tab > Copy Reference

   

   You can paste it anywhere and it will look like:

   C:/Users/username/.IntelliJIdea14/config/scratches/scratch

3. Right click on the tab > Rename File...

4. Right click on the tab > Local History > Show History

5. In .idea\workspace.xml it looks like:

   <file leaf-file-name="scratch" pinned="false" current-in-tab="false">
     <entry file="file://$APPLICATION_CONFIG_DIR$/scratches/scratch">
       <provider selected="true" editor-type-id="text-editor">
         <state vertical-scroll-proportion="0.0">
           <caret line="4" column="17" selection-start-line="4" selection-start-column="17" selection-end-line="4" selection-end-column="17" />
           <folding />
         </state>
       </provider>
     </entry>
   </file>
