Uploading PSD files not possible I have created an Asset field type and have the "restrict file types" option not checked.

When I attempt to upload a file with extension .PSD i get the message Upload failed for 020516_Action-Buttons_Desktop.psd. The error message was: “Error uploading the file: This file type is not allowed”

Is there a setting someplace else thats preventing this?

I also tried checking the restrict option and selecting "Photoshop file". But this also did not work.
You can add the psd extension to extraAllowedFileExtensions in your config file. 

'extraAllowedFileExtensions' =&gt; 'psd'
