The copy and replace feature is not working for me. I'm trying to copy a directory with other folders in it to a back up external drive. The first copy worked fine, however every time that I try to replace the back up copy with the latest copy, it does not replace it merges instead. For instance, I have a folder with folder for data for each year from 2005 to 2010. Somehow 2005 data as well as other years got all jumbled up into each others folders.
Also, If i deleted a folder from my original directory and I do a copy and paste, that folder still appears in the back up directory. It should be deleted. Please help.
