title: Django MEDIA_ROOT pointed to network drive
body: <p>I'm trying to get files uploaded through the Django admin site to be placed on a network drive. Lets say the path to this drive is '\\FILESERVER\Django'.</p>
  
  <p>My initial thought was to just set my media root to the same path I'd use to access the drive via File Explorer:</p>
  
  <pre><code>#settings.py
  MEDIA_ROOT = r'\\FILESERVER\Django'
  </code></pre>
  
  <p>An Example Model:</p>
  
  <pre><code>#models.py
  class Article(models.Model):
      title = models.CharField(max_length=128)
      pdf = models.FileField(upload_to='articles', blank=True, null=True)
  
      def __str__(self):
          return self.title
  </code></pre>
  
  <p>But when I upload a file, It just creates the folder on my local C: drive. 
  (e.g. C:\FILESERVER\Django\articles). Is there a way I can tell Django that this is supposed to be a path to a network drive?</p>
