title: Open an unspecifiable Folder with applescript
body: <p>I'm trying to write an AppleScript for a Keyboard Maestro Macro, which opens the pictures folder of a camera SD or CF Card in an existing Finder window. 
  This is my current code, which opens the mounted Volume.</p>
  
  <pre><code>tell application "Keyboard Maestro Engine"
      set KMVarPath to get value of variable "path"
  end tell
  
  
  
  set the_string to "/Volumes/" &amp; KMVarPath
  set the_path to (POSIX file the_string) as string
  
  tell application "Finder"
      activate
      if window 1 exists then
          set target of window 1 to the_path
      else
          reveal the_path
      end if
  end tell
  </code></pre>
  
  <p>The problem is those folders are called ie 276ND2XS or 105ND800. I'd like to specify the 'suffix' (ND2XS/ND800) and open the folder with the highest 'prefix' number.</p>
  
  <p>Is there a way to do that?</p>
  
  <p>And for convenience, is there a way to check, whether the volume is an SD or CF Card? Or do I have to check via the name (NIKON D2XS / NIKON D800)?</p>
