I back all my zip files up onto DVD, okay so i';d have to reinstall the whole lot in a mammoth session - not looking forward to that and then I have everything on an external HD and on my internal HD - there' s Poser stuff coming out of my ears.  My next step is to burn my individual Runtimes as is ont DVd - just need to buy a shed load of the darn things and STOP buying content!!!!!!
