How to exclude a sub folder from iCloud drive in macOS Sierra? I have my Documents folder synced with iCloud drive, I want to exclude some sub folders from the iCloud drive is there a way to achieve this?
Adding one empty file named .nosync to a folder will prevent that folder from syncing.

You can also use this as a file extension to specific files, but the folder treatment is quite useful.

Once you've had a folder sync, you can now also prevent it from syncing on some (or all endpoints) with a utility named Bailiff, if for some reason you don't want just to delete the files from iCloud entirely and instead want to prevent the next "initial" sync.
