Hello, I just bought a macbook and this is the first time that I am using the Mac OS. In windows, when you download a file, it asks you where to download that file. And you can browse to the folder you want to download in and you choose it. However, in Mac, when I download a file, it just gives you the choices of Network, the HD, Pictures, Applications, and etc. Just the BIG folders. But I cannot choose to save, let's say a picture file, within a folder that is within the Pictures folder. Is there an option to change the save method so I can choose a more specific place in which to download files?
