Please excuse me chuckling - I couldn't help it. If you remove items within lists, there may be other pointers / references to the same item in other lists which still exist. The item you have removed from one list is still listed in others. So it doesn't go into the Unlisted folder.

Eg if you have used the same waypoint in 10 lists. when you decide that you don't want that item in that list, then rather than delete it, you can remove it. That entry just vanishes. It doesn't go anywhere. Thats because there are still 9 pointer floating around in other lists.

However, when you remove the last one - it doesn't just vanish - becasue that would delete the data itself from the database - rather than just the pointer to it. So It goes into the 'Unlisted data' folder. (Ie it is a data item that does not appear in any list). Its quite a neat way of oragansing

Stay away from Delete. Instead, use Remove. You can then go to the Unlisted data - and see if you really want to get rid of the things that do not appear anywhere else in your database. But until then they are all collected together.

So what you said is exactly correct. That is what happens. The Unlisted data contains the items that do not appear in any other list in My Collection

Delete is Dangerous. But Basecamp gives you a warning: "Items will be deleted from All lists" - so if you Delete just one of those 10 pointers that I mentioned earlier - you have asked it to delete the data to which it is pointing. it will delete very single pointer from the 9 other places that it has been used. It will not then go into the Unlisted folder.

There's an option to tick to prevent that 'Delete' warning message popping up. I don't know how you put it back if you have accidentally ticked it. I like it to pop up to remind me.

Basecamp has pretty deep 'Undo' stack which can often get you out of trouble when you do something in error, or you just "see what this does".
Ah yes that will destroy my entire route. That's very handy, I wished I'd known that before I pressed it.

Undo.

I previously never deleted any waypoints / routes because of the warning, un-intended consequences and all that.

At least I now know what the consequences are!
