The interface presents 4 buttons and a selector. Overwrite and Skip buttons have clear functions and raise no questions, but the funcions of OK/Cancel buttons are not that clear inasmuch as they operate at a different level:
The Ok button is designed to execute what is selected in the options list, but then it should be next to the selection and labelled 'Excute Selected action' (and dismiss the tooltip).
The 'Cancel' button is relevant to the Copy itself, in which case it should be labelled 'Cancel Copy' to make things clear.
The placement of the buttons should be linked to their functions : it would be logical to have 'Overwrite' 'Skip' and Selector + 'Execute Selected' aligned vertically, to show they all target the collision in question, while 'Cancel' should remain where it is now (at the bottom Right corner) to show it is linked to a different level of action.
