There are some settings which can help control how files are dispatched and protected.

frontend.downloads.hidden - if this is set to 'y' (default), Kartris will hide the path of a file from the user and stream it them instead. This provides additional security for files.

frontend.downloads.daysavailable - this is the number of days after a purchase that downloadable items are available for. The default is zero, which means there is no limit. If you only want a customer to be able to retrieve the download for 2 weeks (for example) then you can set this to 14 days.

frontend.downloads.instant - for security, you may only want files to be available to purchasers once you have set the order status to 'dispatched'. This is useful if you are concerned about fraudulent orders, which may be more common for downloadable items where no physical delivery address to retrieve the goods is required. If set to 'y' files will be available from the 'my account' area immediately when the order is paid and called back. The default is 'n'.
