That is the problem......no point in having a file if your program cannot open it....or the PC does not run the program or recognise the hard drive the file is stored on or the interface you are using....I do not think I will risk it after my Vista experience. The companies who made the hardware got no support from Microsoft when their products would not work. Some even pulled the product and discontinued support whilst others had to produce their own drivers to get the stuff operating. Meanwhile I had a host of uselss hardware including printers and various memory sticks plus many other external devices that worked perfect on XP but crashed and burned the second I connected them to Vista. I will wait till all the bugs are sorted and my PC and laptops give up the ghost before considering an upgrade. Perhaps DAK has a point about why he prefers Linux.
