This is kind of true, in that a data engineer is probably mostly thinking about data that already exists somewhere in a consumable fashion (a database, S3, an API, whatever). These usually have some default access method either built in or prescribed by devops/security/another team. However, anyone who's ever worked with a server should be able to talk about moving files on and off of it - at least come up with one reasonable way to do it.
