Dont use a hardfile use a real file. A directory.................just simply attach your old Amiga Harddrive to your PC and copy its contents to a folder in Windows................name them the same (Workbench, and Work.or whatever you call yours) then in WinUAE select a config exactly as the Amiga you took the HD from (to make sure it works.later you can change it). select ad a Hard drive and select Workbench and Work. and boot!
