I had copied some files- including ISO files to my USB drive from MAC Mini Intel.When I use the USB drive in WinXP, I see 5-6 copies of the same file but only one on Mac !!!
Yes, they all appear on USB and I am able to look at the properties-they are identical. But, if all of them were real then I would have run out of space on my USB.
Too many ._DSStore and trash files on USB
