closed file
Investigation officially concluded
A closed file is a case, investigation, or record that has been concluded and is no longer active.
In law enforcement and administration, files are closed when matters are resolved, abandoned, or reach a dead end: The detective marked it a closed file after the suspect died.
The phrase implies finality—no further action expected or warranted.
