title: Odoo[v9] store files in filesystem
body: <p>My question is about storing different files in the filesystem and not in the database. I am using Odoo version 9 and everything I found is for Odoo[v8]...</p>
  
  <p>I have read something about a "default" storelocation, but I could not find it in the filesystem... Does anybody know where I can find this?</p>
  
  <p>I also tried to set a parameter to the "binary" field, but this does not work. When I like to save my entry Odoo tells me, that I have maybe forgotten a required field... Here is my code:</p>
  
  <pre><code>class product_file(models.Model):
     _name = 'product.file'
  
     name = fields.Char(string='Bezeichnung', required=True)
     description = fields.Text(string='Beschreibung')
     data_file = fields.Binary(string="Datei", required=True, attachment=True)
  </code></pre>
  
  <p>Can anyone please help me!</p>
  
  <p>Thank you</p>
  
  <p><strong>Edit:</strong></p>
  
  <p>Found the solution:</p>
  
  <p>If you want to use the parameter "attachment" you are not allowed to set the field as required... That was my mistake</p>
  
  <p>And the other point, yes, the default location can be found in the config-file (Thanks to Prakash Sharma)</p>
