# What does "You stopped this. Nothing was removed — this is a simulation" mean?

You were running a preview (a simulation) that only works out what **would** happen. Stopping it changes nothing — no files were removed or moved, because a simulation never touches files.

Run it for real when you're happy with what it showed.
