Thanks for the replies. I don't notice any obvious degradation in the pictures after transfer so I think you are correct in that it should not make any difference - I was just wondering if there was something the experts might know about.
With regard to using PC Linq it seems to work fine on both my computers that are using XP however I have noticed that it is better to delete the old files first before trying to transfer the new ones in for some reason? This is not always the case but I find everytime I transfer and pick up a problem all I have to do is delete the old files and the transfer then takes place seamlessly. Thanks
