Reading an earlier thread reminded me of an issue I have with saving my gazillions of digital photos which I have saved in "My Pictures" on my pc.

I bought an external hard drive to save them on just in case my pc crashed and I "lost" them all.

The thing is that when I load some additional photos onto my pc and then later decide to add these to those stored on the portable hard drive, my system does not recognise that it is duplicating most of the photos which are in "My Pictures".

Is there a way of fooling the system so that only the later additions get added to those already stored on the external hard drive?

Hope this makes sense!
