moving filter from FF4 to FF5

Sorry if this is been cover time and time again, I cant seem get my filters for FF4 to FF5
I was told to "just need to go to ~/Library/Application Support/Filter Forge 4/My Filters copy all the files there and just paste them into ~/Library/Application Support/Filter Forge 5/My Filters"

I dont even see "My Filters" folder on my system? and not Filters Forge 4 or 5 in Application Support/

I read that these files will need to be copied:
Library\
Library.xml
LibraryStructure.xml


I see LibraryStructure.xml

I DONT see Library.xml

and both Library\ contents look the same.

I am sure this something basic I am not getting, but I would appreciate if someone could just clear up these basic issues for me.

Should I just delete the FF5 folder and start a fresh install?
