short_answer: "They're safety checks. Removal always keeps one copy, so select which copy stays with the round selector; Storage Studio never removes every copy of a file. To delete a file completely, remove the last copy yourself in Finder."

# Why does it say "Pick which copy to keep first" or "At least one copy is always kept"?

Both are safety checks. Removing duplicates always means keeping one copy, so Storage Studio needs to know which one stays — if none is selected you'll see *"Pick which copy to keep first."* Select one with the round selector and try again.

*"At least one copy is always kept"* appears if a removal would take every copy of a file. The Duplicates window never does that. If you really want a file gone entirely, delete the last copy yourself in Finder.
