Assuming it is this NavSync script, that doesn't sync files; it is an alternative to Navigation Lock where going up or down in the folder on one side is done in parallel with the folder on the other side (which may be a different location which mirrors the first one).

If you want to synchronize files, see:

If neither of those does what you need, you can also tightly integrate third-party diff/sync tools into Opus:

Thank Leo, understood. However if I use opus directory to sync 2T it will take me a week. So this is not an option.
