Alas, while Windows 7 lets you pin programs and individual files to the Taskbar, it doesn't let you pin folders. However, there's another lightning-fast way to access a favorite folder, and that's by setting up a keyboard shortcut. Here's how:
1. Open Windows Explorer and navigate to the folder in question. Let's say it's called "Client Files" (which is exactly the name of the folder Jim's after).
2. Right-click the folder and choose Send to, Desktop (create shortcut).
3. Now minimize all open windows and find the newly created shortcut icon on your desktop. It'll be labeled Client Files - Shortcut.
4. Right-click that shortcut and choose Properties.
