How do I easily switch to an open folder on a mac?

In windows, which I'm used to using, I can see all my opened folders in my vertical taskbar, all i need to do to switch to another window is click on the folder in the task bar.

There's no taskbar in mac, and when i have a lot of folders opened, ie, lots of finder windows, how can I switch between them?

The way i'm doing it is, i put expose on an active corner and switch that way. However that's still damn hard, because first i have to bring up expose, and then find my window. The folders are placed in a random position between opened apps, the folders are not in a list, and on a big screen i have to scan the whole screen in order to find the one i want... etc.

Is it really this hard just to switch to a different folder on a mac? :(
