Can I open and use a .RUF file sent me?
Samsung sent me a firmware update for my DVD recorder that ends in .RUF and I get a screen saying I should choose the application to open it. Have no idea what application. The suffix.com site was no help. Is this like the .exe files that Mac owners continually get because sites don't know we can't use them?
