Okay,I'm looking to take a back up of my media folder to an external drive on an ad hoc basis. If I go into my media folder and select all movies and copy them to the external drive, I want to avoid copying over existing files. I get the prompt to skip, replace or stop. If I press skip for each file then it does skip them. If I check the apply to all and then hit skip, it starts to copy all files i.e. 500+ movie files instead of only the 20 new files that I would expect. Does anyone else see this or am I doing something wrong?
