The same applies to two identical snapshots. - However, if the two clones are in the same directory, and the data is not used anywhere else, then that data will be represented in the directory's exclusive size. + - The exclusive size can also be described as the amount of space which would be freed if the corresponding object were to be deleted. - Unlike other size metrics, adding up the exclusive size of all items in a directory may not necessarily add up to the exclusive size of the directory. - **Shared** size
