SynchronizationCriteria.Either Nothing to synchronize ?

I'm trying to sync a local folder to NAS. problem, upload failed because of loss of network connectivity, the file was not sent completely, when I try to sync again, it does not update the file.

it is true that the file in the NAS is with a more recent date, but as the size is different it should upload the file

code:
synchronizationResult =
session.SynchronizeDirectories(
SynchronizationMode.Remote, @"d:\12ch",

"/DESENVOLVIMENTO/Teste", false,false,SynchronizationCriteria.Either);

If you have both criteria selected, the size matters only when timestamps match.
See https://winscp.net/eng/docs/ui_synchronize#criteria

You may want to try the Mirror mode:
https://winscp.net/eng/docs/task_synchronize_full#mode

On the next time, do not abort the synchronization, during temporary connectivity problems. That should allow WinSCP to resume the transfer once the connection is restored.
