There is a huge trend back to PC in the photo community. Sorry you had a bad apple. And I have implemented my workflow because I had lost photos from using Adobe Elements several years ago. I also lost images from export direct from a card into Lightroom. I now copy the files to a folder and import from the folder leaving the images in the folder along with the catalog. And I usually do the download/copy thing and leave it while my husband is doing something that won't cause conflict
