I was trying to drag the blue application folder to the dock to make it available to make stacks. Instead it started making copies of it self ( I do not know how many copies of the same files it made. ) for the dock. I stopped the copying process. However, I now had 223,000 files to delete. Because I was using file vault the trash was emptying securely. Unfortunately, I let it run over night for 12 hours until I stopped it and remove the rest of the files using regular trash. Did I damage my disk or reduce its lifespan by doing this?
