Syntax

public SynchronizationResult SynchronizeDirectories(
    SynchronizationMode mode,
    string localPath,
    string remotePath,
    bool removeFiles,
    bool mirror = false,
    SynchronizationCriteria criteria = SynchronizationCriteria.Time,
    TransferOptions options = null
)

VB.NET

Public Function SynchronizeDirectories( _
    ByVal mode As SynchronizationMode, _
    ByVal localPath As String, _
    ByVal remotePath As String, _
    ByVal removeFiles As Boolean, _
    ByVal Optional mirror As Boolean = False, _
    ByVal Optional criteria As SynchronizationCriteria = 1, _
    ByVal Optional options As TransferOptions = Null _
) As SynchronizationResult

Parameters

Name	Description
SynchronizationMode mode	Synchronization mode. Possible values are `SynchronizationMode.Local`, `SynchronizationMode.Remote` and `SynchronizationMode.Both`.
string localPath	Full path to local directory.
string remotePath	Full path to remote directory.
bool removeFiles	When set to `true`, deletes obsolete files. Cannot be used for `SynchronizationMode.Both`.
bool mirror	When set to `true`, synchronizes in mirror mode (synchronizes also older files). Cannot be used for `SynchronizationMode.Both`. Defaults to `false`.
SynchronizationCriteria criteria	Comparison criteria. Possible values are `SynchronizationCriteria.None`, `SynchronizationCriteria.Time` (default), `SynchronizationCriteria.Size` and `SynchronizationCriteria.Either`. For `SynchronizationMode.Both` `SynchronizationCriteria.Time` can be used only.
TransferOptions options	Transfer options. Defaults to `null`, what is equivalent to `new TransferOptions()`.

Return Value

SynchronizationResult. See also Capturing results of operations.

Exceptions

Exception	Condition
InvalidOperationException	Session is not opened.
ArgumentException ArgumentOutOfRangeException	Invalid combination of values of `TransferOptions` properties, `SynchronizationMode`, `mirror` or `SynchronizationCriteria`.
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 uploaded or downloaded file.
