Question about deleting collections

[roadhazard]

I was wanting to delete some of the auto-generated collections and got this message when I attempted to do so. Silly question but will this delete the movies from my disk drive? If not, I'd suggest adjusting that wording and make it crystal clear that local media files will not be deleted. 

Thanks

It scared me too lol, it just deletes the "collection" not any items in it
