Look in the OBS top menu, Scene Collection.
Inside you'll see the way to create multiple scene collections.
To complete remove a scene/source, just delete it. If you added the same source in multiple scenes you need to remove this source from each scene.
As you look new to OBS, please take a look at

Thanks Pai.
I am new and not new at the same time. I've been with OBS for close to a year now.
First I would like to know if I can open totally different OBS files like I can in most other programs?
In each OBS file I would have its own scenes/sources etc. None of these files would know anything
about each other.
As far as deleting scenes/sources are concerned, I have done that many times before, but OBS seems to
have a memory of its own.
I will delete a source but when I try to create a new one it will still list its name in the names of sources!
Same goes for scenes. I will delete a scene but its name will still be retained on OBS's memory and it will tell
me I can't create a scene with that name because it already exists!
I don't want to create Room1, Room2, Room3, Room4 for the same room! It obviously would get confusing.
I want to delete Room1 and then create a new scene/source with the same name (Room1).
