# What technology does Storage Studio use to transfer files?

We don't publish the details of how transfers work under the hood, but here's what it means for you: Storage Studio uses a mature, widely trusted transfer engine. It talks to each service the way that service expects, checks what's already in place so only new and changed files are sent, and copies before removing anything on a Move.

You never interact with the engine directly — you just choose what, where and when.
