How to copy files (when file already exists)

[GIZBUG]

Trying to copy 100GB from my NAS to an external HD on my iMac. However when I select all the files, and begin to copy, I am running into "The operation can't be completed because an item with the name xxxxxxx already exists" and it stops the whole operation.
How can I prevent this, so I can copy everything over? I know on my old PC, I could just overwrite all and it would keep copying, not stop the whole operation.

Thanks

I would think it is due to you not copying the directories containing the files. The only way that error should occur is if you have duplicate files in a directory structure with the directories not being copied with the files. As you would have been warned with the same when you originally put the files on the NAS. On your old PC you were not copying your files entirely but losing all the duplicates that were being overwritten. Solution is too copy properly preserving the directory layout on the NAS.

Ended up plugging external into nas and copying

I have seen this same annoying issue when trying to copy files from my media server (a 2014 Mini) over my LAN (gigabit ethernet). It may have been related to the slow internal hard drive on the Mini, because I don't have the problem copying files from the SSD on the same machine.

Anyway, I think it's a bug of some sort, where the Finder gets confused when a network device is slow to respond. It only seems to happen when copying a bunch of files and the error message doesn't make sense.
