I have installed MySQL on my local Windows computer.  It is working and I can access the sample databases.  I also have another MySQL data folder that contains copies of my production databases.  How do I open this "second" data folder?  I can copy it locally.

You can only open one data directory at a time.  to switch to the new directory, shut down mysql, Find your my.ini file, open it and change the data-dir entry to the new location.  Then restart mysql.  Note that this assumes that the new data dir is valid, meaning it includes its own mysql schema, etc.  Another thing to note is if the ib_logfile's on the new directory have different size as the original one.  If so you either make another change in your my.ini (look for something like innodb-log-file-size and set the value to the size of the new files), or you can delete the existing ib_logfile's so mysql will create new ones on startup.
