A few years ago I lost several GBs (thousands of rendered images) when I stopped a long move action midway. I tried to resume the process by just repeating the directory move, unsuspectingly expecting that the existing files in the destination directory would be left alone and new files just would be appended, ala Windows (since at least 95). I was unpleasantly surprised to learn that on OSX "Warning: This action will overwrite existing directory" means the destination directory will be wiped out prior to starting the move. Talking to other Mac users, this seems to be common knowledge - I guess only Windows users moving to OSX should be wary.
