There are those among us who carefully lay out hierarchies of folders, each clearly named, in which to store the many documents we create. These folks can very quickly access, for example, the budget spreadsheets from Q2, three years ago, for the Southwest region engineering departments. Or whatever else they need.
These lucky people probably also keep very neat desks. How nice for them.
For the rest of us, fortunately, there are Windows 7 Libraries: "virtual folders" that can let us see the contents of dozens, even hundreds of folders in a single window—as if they were all in one folder—regardless of their actual folder location.
So no matter how haphazardly we may store things on our hard drives, we can easily access and browse through documents that logically belong together, since they appear as a single collection.
Here are some things to know about libraries (visit the links for more details):
The more you experiment with libraries, the more useful you'll find them. For my part, I'm glad all my important stuff is on my system, and not on my desk.
Because, if I had to find something on my desk, I'd have to move all this stuff to the floor, and that would, you know, create a tripping hazard.
