You select a piece of text, right-click and select Copy. As the name suggests, you have now have a copy of the text in the copy vault (or clipboard if you prefer) untill the computer dies.
Now the lie, if you do the same with a file, you dont get a copy in the copy vault. You get a copy to the file path and when you do a paste, then and only then a copy is created.
It the simple case, everything works, but if the "marked for copy in the future" file is deleted or the system has no longer access to it, instead of a copy you get an error on paste.
If you wanted to actual make a copy, you could make a hardlink if the files is on a physical filesystem, create an actuall copy in memory if the file is small, or just create an actual copy in worst case.
But the problem is not that fake copy is default, the problem is that there is not an option for the actual copy. Bellow the Copy option should be a 'Copy for real' option.
