The 
amount of development in an area is something you can't
control. For example, one square mile of city streets will make a larger
file than one square mile of wilderness with a few hiking trails.
The 
amount of territory you include in a map is a major factor. The
more square miles or acres you include, the bigger the file size.
So, what does this all mean in real estate terms? The following table
shows a few examples of high- and medium-detail Custom Map File
sizes, and how long it took the computer to build them. These examples
were prepared on a Pentium
 III with 512 MB of memory, using simple
rectangle map borders:

The lessons in the Quick Reference section were written using
MapCreate's default settings, with 
high detail and all categories turned
on. If your first maps don't fit your MMC or SDC, refer to the online
Command Reference section for more detailed instructions on
controlling file size.
