Workarounds for common server issues 

Workarounds for some server issues are not enabled by default because detecting them automatically would be troublesome. They can be enabled by setting the following properties of Sftp.Settings to true:

Property Purpose
DisableSftp4 Disable SFTP v4 and only use v3.
Workaround for some broken SFTP servers that report 'Unsupported operation' error.
DisableTransferQueue Disable queuing of read and write requests.
Workaround for SFTP servers that don't handle the request queue properly.
UseSmallPackets Use small data packets (4KB each) during upload and never split them.
WaitForServerWelcomeMessage Wait for server SSH protocol welcome message before sending a client message.
Workaround for servers that improperly discard client messages preceding the server welcome message, causing a 'Timeout exceeded while waiting for welcome message' error while initiating the SSH session.
TreatUnknownItemsAsFiles When getting directory content, each item should have an information about its type (file / directory / symlink etc.). Some SFTP server does not provide this information at all and the GetItems methods throws an exception '{itemname} is not a file or directory'.
To suppress this exception and to force the component to treat all such items as files, set the TreatUnknownItemsAsFiles setting to true.
