The operation can’t be completed because one or more required items can’t be found. (Error code -43)

I have imported a bunch of information and files from my camera on the desktop of the computer.

When trying to copy the mp4 files, CLPR folders, or all of the content onto my Seagate Hard drive i get the following message:

The operation can’t be completed because one or more required items can’t be found.

(Error code -43)

My drive is formatted in disk utility as ExFat if that helps.

I am hoping to import the files to edit and/or work off the drive if possible on another mac.
