Any way to export imported source documents from OneStream to an External folder?

Dim profileKey As String = si.WorkflowClusterPk.ProfileKey.ToString
Dim scenarioKey As Integer = si.WorkflowClusterPk.ScenarioKey
Dim timeKey As Integer = si.WorkflowClusterPk.TimeKey

Dim sql As New Text.StringBuilder
sql.AppendLine("SELECT SourceFileName, SourceFileBytes")
sql.AppendLine("FROM StageArchivesInformation With(NOLOCK)")
sql.AppendLine(String.Format("WHERE Wfk = '{0}'", profileKey))
sql.AppendLine(String.Format("AND Wsk = {0}", scenarioKey))
sql.AppendLine(String.Format("AND Wtk = {0}", timeKey.ToString))

Dim SourceFileName As String = String.Empty 
Dim fileBytes As Byte() 
Using dbConnApp As DbConnInfo = BRApi.Database.CreateApplicationDbConnInfo(si)
    Using dt As DataTable = BRApi.Database.ExecuteSql(dbConnApp, sql.ToString, False)
        If (dt IsNot Nothing) AndAlso (dt.Rows.Count > 0) Then
            For Each dr As DataRow In dt.Rows
                SourceFileName = dr("SourceFileName")
                fileBytes = dr("SourceFileBytes")
            Next
        End If
    End Using
End Using

BRApi.Utilities.SaveFileBytesToUserTempFolder(si, si.UserName, SourceFileName, fileBytes)
