# What happens if the same file changes on both sides of a two-way sync?

That's a conflict, and Bidirectional sync records it in the transfer's log rather than silently picking a winner. Select the transfer in Data Transfers and read the **Log** card to see which files were affected.

To keep conflicts rare:

- Run the sync often (a schedule helps), so each side has fewer changes waiting.
- Avoid editing the same file in both places between runs.
- Close a file before a run if you're editing it.

If you find a conflict, open both versions, keep the one you want, and let the next run carry it across.
