File transfer command statuses

If a file transfer connection verification fails in runtime, you can open the window, which displays a command status code, description of the command status, and a corresponding libcurl error code (if applicable).
TIP: The command status code may correspond to multiple libcurl error codes. Only the applicable libcurl error code displays in the window.
In View Designer, the
TransferStatus
 field for
Upload
 and
Download
 file transfer commands displays the status code of the last command execution.
