This is the MapV representation of a well-known directory hierarchy, the Linux kernel source tree. (Version 2.4.7, if you have to know :-)) All the files are there; however, since most of the directories are collapsed, you don't see very many of them.

Let's go to the drivers directory, which appears to be the largest one. If we expand it (by one level), we can see its subdirectories. Note how its entry in the upper-left pane has expanded as well.

Let's have a closer look at video, shall we?

Expanding this directory, we see files! Note the varying sizes, with larger files (and the three subdirectories) toward the back.

If any one of them piques our interest, we can always click on it and zoom in for a closer look.

Or, if we wanted to see everything (and I do mean everything), we could perform an "Expand all" on the root directory. Here you can see all 9,221 files (in 494 directories) of Linux source code and documentation. Such a lovely sight. . . .

Now, let's switch gears into TreeV mode! We're looking at the top-level linux directory again, with the entire drivers hierarchy already expanded. The (tall) grey blocks represent collapsed directories. And remember, in TreeV mode, it's the height that's proportional to size!

Here is the drivers directory again. The "X" squares are place-holders for directories that have been expanded (a few of which are visible here, farther back). There's only one actual file in this directory: Makefile.

If we move down and to the right a bit, we come upon the char directory, which holds some of Linux's character device drivers. Apparently it has a few subdirectories. Let's go to that one in back there . . .

. . . ftape. This one has three subdirectories of its own. What might that larger-looking file there be?

Ah, the release notes for the driver.

If you ever lose track of where you are, just press the button with the birdie on it, and you'll fly up, up, up for an aerial view.

("Look at all the files! I can see my home directory from up here!")
