Syntax
public TransferOperationResult GetFiles( string remotePath, string localPath, bool remove = false, TransferOptions options = null )
Public Function GetFiles( _ ByVal remotePath As String, _ ByVal localPath As String, _ ByVal Optional remove As Boolean = False, _ ByVal Optional options As TransferOptions = Null _ ) As TransferOperationResult
Parameters
Name | Description |
---|---|
string remotePath | Full path to remote directory followed by slash and wildcard to select files or subdirectories to download. To download all files in a directory, use mask * . |
string localPath | Full path to download the file to. When downloading multiple files, the filename in the path should be replaced with operation mask or omitted (path ends with backslash). |
bool remove | When set to true , deletes source remote file(s) after transfer. Defaults to false . |
TransferOptions options | Transfer options. Defaults to null , what is equivalent to new TransferOptions() . |
Return Value
TransferOperationResult
. See also Capturing results of operations.
Exceptions
Exception | Condition |
---|---|
InvalidOperationException | Session is not opened. |
ArgumentException ArgumentOutOfRangeException |
Invalid combination of values of TransferOptions properties. |
SessionLocalException | Error communicating with winscp.com . See the exception documentation for details. |
TimeoutException | Timeout waiting for winscp.com to respond. |

Remarks
Event Session.FileTransferred
is raised for every downloaded file.
The download aborts on the first error. See how to implement recursive directory tree download with custom error handling.

In this example the JScript script is embedded into WSF file, to allow access to enumeration values.
