Diff between getExternalFilesDir and getExternalStorageDirectory()
<p>I understand that ExternalFiles is to be used on API 8 and up and getExternalStorageDirectory is for 7 and down. However I am a little confused between the use. For example I wanted to check that a folder that exists and previously you would use something like:</p>

<pre><code>File ChildFolder = new File(Environment.getExternalStorageDirectory() + "/ParentFolder/Child");
</code></pre>

<p>However every example I see says to use getExternalFilesDir (null), File.ext. Since I am above API 8 I want to use this method but how do I just check for a folder? I will check for a files existence at another point but for now just want to see if the folders exist??</p>

<p>TIA
