When looking at a file click the green download button to the right of the file details:
This will then start downloading your file.
Please note to keep this site free there is a limit of the amount of files you can download in a day. This limit is quite high and a number such as 50 per day. If you reach this limit you will not be able to download for the rest of the day. Come back in 24 hours and you will be able to download again. This helps cut our bandwidth costs and besides I have not met any people who change their ringtone 50 times a day.
