Troubleshooting & messages · Moves and copies that didn't finish
Why does it say Storage Studio was still checking its copying tool?
Short answer: Storage Studio was still confirming its built-in copying tool was ready (just after launch). Nothing changed — wait a moment and try again.
Right after Storage Studio opens, it checks that its built-in copying tool is ready. If you start a move during those first moments, it declines rather than risk a half-ready copy. Nothing was changed.
Wait a moment and try again — this clears by itself within seconds of launch.
