You can see the name and location of the active catalog by going here: Preferences / Catalog Settings / General
As mentioned by Brad, you can check the name of the catalog by going to Preferences> Catalog Settings> General
and it also displays the name of the catalog at the very top of your screen in title bar.
And to get all the subfolders, make sure you have the subfolders option checked or included at the time of import.
Lol so it does! Man I looked all over it - newbie getting used to the interface
It is not folders I am missing but files form the imported sub folders. Anyway, indirect thanks to an earlier post, I have reverted back to 6.1.1 and it works perfectly - so something to add to the 6.2 bug list. Yes as others have noted, and while I am totally LR inexperienced, the 6.1.1 import interface looks better
