    Hi. I'm trying to find an app that will enable me to copy and paste multiple files and folders from my mac to an external hard drive which has the same named folders and files but I only want to copy across and update new files and folders and not have files and folders which have changed on my mac copy across to the external hard drive (I've altered some of the original files in the folders and I don't want to copy those across, just keep the originals). I've been searching for an app to automate this but only found sync programs for the mac and I'm not sure how to use them. Can anyone suggest some apps to try or a particular app that would do the job please? It would need to be compatible with macOS Sierra.

    Just to be clear: What I mean is that some of the same named files in the same named folders on the external drive have been experimented with by me and altered but overwritten to the same named folder on my iMac hard drive. So when I go to copy and paste the entire folder to the external drive I'm worried that the changed files on my hard drive will overwrite the originals with the same name on the external drive, which is definetly not what I want to do. I want to just copy across any additional content I've added to that same named folder (and others in exactly the same situation) because the same named folder on my hard drive also contains additional purchased music and so on. The same named files in the folder on my hard drive are not files I want to have copied across to the same named folder on my external drive.

    My problem is I have a really lot of these such folders containing GB's of files so I'm trying to automate the whole process rather than trying to do it manually. Plus, I've lost track of what files I've both added to the folders and do want to copy across to the external hard drive with the same folder name/s for the files and which ones I've experimented with and overwritten on my hard drive and do not want to copy across to the external hard drive that contain the same folder names as those files' folder names on my internal iMac hard drive.

    I hope that better explains my situation and hope you can see my predicament - where talking a very great amount of files and in total a huge transfer of GB's of files.

    Thanks in advance. Any help much appreciated.

    The app Carbon Copy Cloner can do this. Just select what folders you want to copy, then make sure you turn on a feature called "SafetyNet". By default the app will replace a new file version over the old one, and having this option on will save the old version in a folder for you.

    There is a free trial you can use to test.
