restoring layouts

I’ve just re-installed wavelab7(mac)
How do i restore the layout setting that i have saved

They should appear in the Workspace menu.

workspace–layout–explore presets?
then what should i do now?
tried to open the .dat files but doesn’t work

no such function was found in the workspace menu.
so i replaced the whole preference folder with the old one (on finder), and that did solve the problem.
very sophisticated and user friendly indeed.
