Getting information from a folder

Hi!
I recently download an application named dropbox. This application create a folder named public so you can share what in it on internet.when you right click on your files it gives you an url address. so you can download your file from everywhere. I want to write a program that write all addresses on a file. the problem is how I could get the specific information from a folder(or maybe folder's properties dialog box ).

thanks

What information are you looking for?

You can access information on files (folders included) by using the File class.
