    Have over 300GB on an external HDD (HFS+) which I need to copy to the Documents folder on
    OS Sierra, is there any good utility to do this?

    I do not trust copy n paste to transfer such a large amount of files.

    I'd trust copy and paste before I'd use a third party. I deal with sample libraries all the time, never had a problem.

    Have you ever tried copying from an external HDD to "Documents" folder in OS X?

    Did you get error messages re: permissions?

    Carbon Copy Cloner is the easy way. You are right to avoid copy and paste. If anything goes wrong then you can't resume the process. Carbon Copy as a trial will let you copy data to a folder.

    Post above this one is right.
    Use CarbonCopyCloner.

    Set it up as follows:
    - connect external drive
    - open CCC
    - select external drive as source, internal drive as target
    - next, VERY IMPORTANT -- you will have to manually UNcheck EVERYTHING EXCEPT the "documents" folder.
    - when you tell CCC to "go", it will clone over ONLY the documents folder and its contents. Everything else will be left untouched.

    Also important:
    Before you do this, I would do a "get info" on the external drive icon.
    Then -- click the lock icon and enter your password.
    Then -- put a checkmark into "ignore ownership on this volume".
    This takes care of any permissions problems.

    A final thought:
    My opinion only, but I don't think it's good policy to have a documents folder with 300gb of stuff in it.
    Those items should be "parceled out" into more folders (or even volumes or separate drives) that are pertinent to what's in them.
    As goes the old saying... "don't keep all your eggs in one basket"....?

    Thanks Fishrrman.

    You have me worried now! When you say it will "clone over" does that mean that any pre-existing documents (in the Documents folders) will be deleted?

    The External HDD does not have a an option "ignore ownership on this volume". I've seen screenshots of this but for some reason "get info" properties does not present this option?

    As for the 300gb in one folder? Surely, OS X can handle this? My concern is that when a backup app like Crashplan is deployed - custom options will have to be set?

    "You have me worried now! When you say it will "clone over" does that mean that any pre-existing documents (in the Documents folders) will be deleted?"

    In a regular clone, YES.
    The files that are currently there will be REPLACED BY the files getting "cloned over" from the external drive. Unless some of them are the same files, in which case they'll get updated or be left alone.

    I believe CCC has an option to (and this may not be the exact language) "preserve newer files, don't delete anything". With this option, files on the source will be copied to the target, but the files pre-existing on the target will be "left where they are".

    I think this choice would work for you. It would merge the contents of both documents folders.

    "The External HDD does not have a an option "ignore ownership on this volume". I've seen screenshots of this but for some reason "get info" properties does not present this option?"

    Look again.
    This time, under "sharing and permissions".
    There may be a "disclosure triangle" you have to click to see the options.

    Personally, I have never encountered a drive or volume that prevented me from doing this.
    (That doesn't mean they don't exist).

    "As for the 300gb in one folder? Surely, OS X can handle this?"

    I will say again (and it could be nothing more than an instance of my own prejudices and superstitions) that one shouldn't keep that much data "in a single folder".

    What the heck do you have in there that constitutes 300gb, anyway?
    If there is a mix of movies, music, pics, other files -- I would break them up and spread them around some.

    BTW, I don't use CrashPlan or waste my time with ANY "online backup".
    I maintain numerous physical backups and keep them dispersed in different locations for safety.

    Just drag and drop, like all Mac file transfers.
