Transferring PC Windows files into Mac computer

Hi there,

I just bought my External Drive SE and I saved my info that was in my Dell (windows). I tried to download the files into my new Mac, and I think that Time Machine might have erased what was on the External Drive, because now I don’t see any of the files that I saved and when I hook up the drive to the PC it won’t even let me download anything… I need help! Any ideas.

Thanks for your time,
