Hidden files and folders.

If I have files and folders hidden on the main drive that the OS is on, will it also hide the same files and folders if I move them to external drive?

If I have files ands folder hidden on the main drive that the OS is on, will it also hide files and folders on an external drive?

Try testing it.
Place a dummy file and folder on main drive then send it to external drive and check to see if transfers as a hidden file/folder.
