Why I can't upload a favicon.ico as an Asset? I'm unable to upload the favicon.ico thought Craft because it says:

Upload failed for favicon.ico. The error message was: ”Error uploading the file: This file type is not allowed“


Why does that restriction exists? I just couldn't find a list of forbidden files.
Can I change that restriction?


I know I can use a FTP client to put the file in the folder, but since I'm doing this site for a friend I just wanted to leave her an easy way of managing the icon.
1) It's not allowed because it's currently not in the allowedFileExtensions config setting.

2) Just add 'ico' to the extraAllowedFileExtensions config setting and you'll be able to upload .ico file.
