Resolved Lost the information column on left side of File Explorer

I don't know what I have done but I have lost the Home Information column on the left hand side of file explorer that shows all the drives connected to my computer I have only got a single box with just the drives in it when I press Windows key + E and when I click on a drive it just goes to that drive and i have a problem getting to my other drives.
Hope someone can help

 

Many thanks Evan that's fixed it
