Windows 10 - Hidden files and folders not showing

[Sydney G]

Latest LR - Win 10
I have WIN 10 set to show all hidden files and folders (including system files).
In the folder containing the catalog, there is / are the .lrcat files and the backup folder.

When I go to backup my catalogs to cloud, It is saying there are THOUSANDS of files / folders.
Why am I not able to see these files / folders for LR, when I can see all other system / hidden files for other apps?

I found solution. There is no way to delete.
