Today a user asked: Where can I get this URL from the file I downloaded?
The answer is to use the MacQuarantinePropertiesMBS class. There you have properties to get he origin URL, normally the website. Also the data URL where the file is located, the time stamp and which app did make the download. Also there is a property to tell you what type of download it is like a web download, an email, an calendar event or an instant message attachment.
