When running windows 3.1 or higher on a 386 or higher machine, you run
windows in what is called "386 enhanced mode." Under this enhanced mode,
you can set up either a permanent, or a temporary "swap file." The
windows uses this swap file to effectively add extra RAM (not hard drive
space) for use by programs under windows. So if you have 6 meg of real
RAM and an 8 meg temporary swap file, windows can utilize a total of 14
meg of RAM. This is what most people refer to as virtual memory.
That extra drive letter you see (Drive H:) is a result of the fact that
your 40 meg hard drive has been "DoubleSpaced" using DOS. Double space
is a program that compresses most of the files on your hard drive,
effectively, "doubling" the amount of hard drive space you have. Since
you have only a 40 meg drive this is pretty much essential. The H: drive
is actually the uncompressed portion of your drive that contains the
information files which contain a map of the compressed portion. Make
any sense? It is not possible to compress the entire drive, only about
90 percent of it.
Hope this shed some light.
