Loaded movieclips and levels

HI

lets say i am using a main flash file to load movieclips

in the child moviclips, i am duplicating a movieclip many times.

now will these movieclips be duplicated into levels separatly or will they take up level space in the main movieclip ?

in other words will each loaded movieclip have its own set of levels or will they exist in the same space ?
