Filem manager use in 20.04 NOOB Question

[mahesh]

I'm new to Ubuntu and I'm trying to see how I can get all of my disks showing in my file manager.

They were there under Other Locations, and in the left column There was what I thought was a collapse button, but when I thought I was collapsing them they dissapeared totally.

How can I add them back to file manager?

Any help appreciated
