When you are in explorer and are manually typing in a long folder path or at a command prompt navigating through many directories, below are two cool tips that will help you save time.
The first is one that I have been using for years. When working at a command prompt, instead to typing in the full text of an item, just hit the tab key to bring up full items. For example, say I want to change the directory to the Windows folder. At a command prompt I would type in CD wind and then hit the tab key and "Windows" will automatically show up. Think of the tab key as a kind of auto complete for DOS. This same technique also works in Windows Explorer.
Another tip was sent in by Robert Warriner also has a similar effect. Instead of hitting the tab key to bring up alternatives, you can use the * wildcard. For example, the command CD wind*\*32\dri* will change your directory to c:\windows\system32\drivers. The * wildcard will also work in Windows Explorer.
