# Transfer Retry Considerations for Preprocessing

When a transfer is retried after a recoverable error or after the preprocessing action terminates the transfer with a retryable error, preprocessing actions may be executed or may be bypassed. These criteria define when preprocessing actions are executed for a retried file transfer.

## Initiator Transfer Retry

- When a transfer retries because a preprocessing action sets the return code to a recoverable error (2, 3, or 4), all preprocessing actions are executed on a transfer retry.

- When all preprocessing actions have executed with return code 0 or 1, the processing actions are not executed on the transfer retry.

## Responder Transfer Retry

- When a transfer performs a checkpoint restart, preprocessing actions are not executed.

- When a transfer is retried and checkpoint restart is not performed, all preprocessing actions are executed.
