using a dynamically harddrive

[Cybershooter]

when i choose a virtual windows xp pro machine as a dynamically harddrive, the file will growing larger as i use windows, as far as this i understand, but when i install for example some applications in xp pro the vdi file grows, but when i deinstall some programs the file size of the vdi will not decrease, so the windows c drive will differ more and more from the dvi file my question is, if that is a normal fact. My second question is, is there a situation that the dynamically vdi file can exceed the size of the harddrive as choosen in the beginning.
