  "text": "A verified copy is a copy that has been checked against the original before the original is removed. It's the reason a move in Storage Studio is safe to stop or retry: until the check passes, your original is untouched. For folder moves in Data Parking, the gear button sets how carefully each copy is checked: Fast (stat compare) — the default. Compares every file's size, modified time and permissions on both sides, and reads the contents of any file whose details differ. Thorough (content hash) — reads every byte on both sides and compares them. Slower; use it if you suspect a drive problem. Off (trust the copier) — skips the per-file check, though sizes are still compared before the original is removed. Moving an app checks every file and the app's signature; offloading one checks that every file arrived at the right size.
