YES, when you open your hdd and you want that folder on your SSD (only a shortcut) not the folder contents. Grab the folder from the hdd and while parking it on your desktop hold cntrl and shift. You will see the folder and an arrow, signifying a shortcut. When you want something out of the hdd hit that shortcut an voila you are in that folder. To tell your computer where you want your downloads to go you need to do that differently. I forget ATM it is under preferences or tools in your browser I think. Google it with they type of browser you are using. Use this search phrase~ " selecting download folder "
Edit: added search phrase
