Ding, ding, ding! We have a winner! Evidently, (I think) during Windows 7 install, I turned on automatic system backup. I did notice that most of the files had a 2014 date on them.
Int was odd that most of the instructions of how to get to the backup controls (from various web site) did not work. Cortana might have worked but I have not enabled it. I have heard too many odd stories.
It turned out very easy to get to. Right click on start menu, select Control Panel, and there it is "Backup and Restore (Windows 7)". Yes, in Windows 10 it shows Windows 7 in parenthesis.
Went into the control panel and found out it makes multiple backups of data files. I deleted some of the old data file backups and cleared lots of room.
Thanks Trouble, that was a HUGE help. I think I will hang around this forum more often. There is lots to be learned here!
