The number of clients is the count of the number of copies of the FileMaker Pro application that are currently accessing a hosted file on the host computer. The number of files open does not affect this count.
Thanks for your reply PhilModJunk.
I'm trying to get to a definition of "accessing a hosted file". If I have database #1 and it has a relationship with database #2 (for example, based on a client ID in database #1, it grabs the mailing address from database #2), does this type of access count toward the maximum number of clients for that second database even though the user has only "opened" database #1? Is that counting as an instance of access in place as long as database #1 is open, or only for the moments when the relationship with database #2 is being referenced on a current layout?
I wish I had 9 machines with FM Pro on them to test this.
If you go to computer #1 and and use FileMaker to open 3 files (Open Remote) on the hosted computer, then go to computer #2 and open 2 files on the hosted computer, your "user count" will be 3-- 2 clients and one host.
Theoretically, if you install a volume license version of FileMaker, you can go back to computer #1, log in to the computer with a new user account, use FileMaker to open some more files and your count would now be 4.
