| 35 | * For Bluetooth, files are received through OPP, and |

| 37 | * as part of a single transaction. |
| 38 | * Hence, a transfer has a notion of being "alive": if |
| 39 | * the last update to a transfer was within WAIT_FOR_NEXT_TRANSFER_MS |
| 40 | * milliseconds, we consider a new file transfer from the |
| 41 | * same source address as part of the same transfer. |
| 42 | * The corresponding URIs will be grouped in a single folder. |
