Automatically downlaod a file from website

Question

Hi,

There are many websites which regularly allows users to download a file (suppose its an .exe) uisng "Save Target As".

I am interested to automate the process where in my application should go the URL every day and check for a new .exe. If it is present download it and put it in any of the partitions of my hard drive.

there should not be any manual intervention in this process of downloading a file.

thanks
