# What does Storage Studio do to my external drive during setup?

Setup doesn't erase or reformat your drive. Storage Studio creates a small folder layout on it — to keep relocated apps, folders, backups and its own settings tidy and separate — and marks the drive as yours.

That mark matters: Storage Studio can always tell your prepared drive apart from any other external disk, even one with the same name, and it only ever manages the disk you set up. A drive that hasn't been prepared is never touched; the app offers to set it up first.

Files already on the drive stay where they are. For choosing a good drive, see [External drives](https://storagestudio.us/faq/external-drives/).
