Hi CPR. I'm Greg, an installation specialist and 9 year Windows MVP here to help you.
This is but one of the problems that cause the most experience experts to recommend NOT using File History because of the many cases we see where data is lost like this.
The actual restore process is outlined here:

File History, Windows file and Image backup are dysfunctional and may be phased out in a future version. But they're not the best choices anyway because after ten years in forums I've seen countless times that files are lost trying to restore them, so feel obligated to recommend choices that work much better and are 100% reliable.
The safest and most reliable method is to sort your files into their User Folders (Documents, Desktop, Pictures, Downloads, etc) and periodically drag or copy them to external or another hard drive.
Then have one other Cloud backup so your files are safe from fire and theft and easily accessible via the internet just like email. Some suggestions to help ease into this habit:
You can drag 5gb for free into OneDrive app to store in the cloud where they are safe from fire and theft. You can also choose to sync the Desktop, Pictures and Documents folders (only) in Settings > Autosave for real time backup.
If you install Google Drive, you can use their new Backup to choose User folders (Documents, Pictures, etc.) to sync up to 15g for free to their cloud in real time.
Or you can drag or copy them to a USB external or flash drive.
Here's how to drag, copy or move large groups of files: https://www.pcworld.com/article/2086566/the-man...
Besides your files you should back up a System Image to use in place of reinstall in 20 minutes. The best free alternative is Macrium: http://www.howtogeek.com/howto/7363/macrium-ref....
There is an easy way to mount the System Image to extract files if needed. Some prefer to move their User folders off of C to make the image smaller so they stay current if you need to reimage C. Here's how: http://www.dummies.com/computers/operating-syst...
I hope this helps. Feel free to ask back any questions and keep me posted. If you'll wait to rate whether my post helped you, I will keep working with you until it's resolved.
