In my window, on the left, is a listing that says "Mail", "Calendar",

The Navigation Pane for Outlook 2003/2007

The file I am describing is the "Contacts" or Personal folder file.

The Contacts folder and the Personal Folders file are not equivalent. The
Personal Folders file contains not only your Contacts, but all the other
folders you have as well, like Inbox, Calendar, Tasks, and Notes.

Within that I have listed all my contacts for all of my salesmen.

You have an entry in the Contacts folder for each salesman's contacts,
correct?

Under that main file

A folder is not a file.

I have constructed lists with all the contact info for each of my
salesmen.

What do you mean by "list"? Do you mean a Distribution List or do you mean
a subfolder?

I want to be able to make a change to the "main" file and have it
update the ancillary files at the same time.

I don't understand what "files" you mean here. Outlook's folders aren't
files and don't contain files. If I were to guess, I think you mean that
you have created multiple Distribution Lists whose members are the names and
addresses of each of your salesmen's contacts and that you want to update
the individual contact record for one of the members and have the address
change reflected automatically in the Distribution Lists containing that
person. That can't be done. Outlook has no facility for that.
