Do I need the Lightroom Library.lrlibrary folder in LR Classic

I recently did a clean install of LR Classic on a new computer.  Along the way, I somehow managed to install LR CC by mistake.  Once I realized I'd done so, I deleted it.

I now have a Lightroom Library.lrlibrary folder in my Pictures folder on my Mac.  The folder contains four subfolders including "users,""TemporaryEdits,""Profiles," and one with a name that contains a set of letters and numbers.  I read somewhere that a .lrlibrary file is used by LR CC but not by LR Classic.  However, I haven't found anything that talks about an entire folder identified as above. 

Do I need this folder and its contents or an I trash it?  If I need it, an I move it to within another folder just to keep my folder hierarchy more to my liking?
