Why do I see a “Put Back” menu item in the trash for only some items?

Question

When I control-click on some files in the trash I see the "Put Back" menu item:

However, on other files I don't see this item:

Why is that?

Answer 1

You only see Put Back if a file/folder was deleted by the Finder, not any other process.

It will silently fail to Put Back if the folder it came from is gone, but it will still offer.
