Azure Web app save temporary files limit
<p>I have need to store files temporary on my Azure web app (app service). I don't have to share these files between web app instances.</p>

<p>I have read (in the <a href="https://github.com/projectkudu/kudu/wiki/Azure-Web-App-sandbox" rel="noreferrer">kudu wiki</a>) that I can use the d:\local for such storage, but what limitations exists regarding the amount of data that can be stored there?</p>

<p>I have also read that it depends on the selected level (sku) of the web app (Basic, standard, premium) but I have not found any exact size limitations.</p>

<p><strong>Is there any way to determine this in runtime using code</strong>?</p>

<p><strong>UPDATE:</strong><br>
When I check the the Environment tab in Kudo on my Basic web app it lists</p>

<pre><code>D:\home usage: 10,240 MB total; 10,072 MB free 
d:\local usage: 230,397 MB total; 198,341 MB free 
</code></pre>

<p>But if I do a check using <code>System.IO.DriveInfo.GetDrives()</code> the D drive lists as</p>

<pre><code>d:\ usage: 32,768 MB total;  12,083 MB free
</code></pre>

<p><em>(Kudo shows a lot more than that for the d:\local drive.)</em><br>
Another peculiar thing is that you can navigate the filesystem in the Kudo console but the files I create on the web app can not be found there.</p>
