Hide files see only folders.

hi just wondering if you can help me with this annoying problem.

When I connect to my work server and go to open a file I see all the files that are in the folders and it takes me ages to scroll down and find the file I want.

Can I have it so i just see the folders, so I can go to that folder and open up the files just in that folder. Easy to do in PC but just just don't know how to do it on mac :s am I being stupid? The other views all so show all files! Using Leopard.

Which of the four options for viewing a Finder window do you use? (Icons, List, Column, Cover Flow)
