# What happens if a Delta Drive file changed somewhere else while I was editing it?

Your edit is never allowed to overwrite a newer copy. If the file changed somewhere else while you had it open — on another Mac, in a browser, or by somebody you shared it with — your version is saved beside it under a name that says where it came from.

The window tells you this happened and waits for you to acknowledge it. Both copies are in your drive, so nothing is lost; compare them and keep what you need.
