Generate folder link manually

Yep, I have that set to WriteMode.Overwrite.Instance, what about larger files?

I am using :

 Private Async Function ChunkUploadAndCreateEmail(path As [String], stream As FileStream, chunkSize As Integer, dbx As DropboxClient, filepath As String) As Task

        Dim numChunks As Integer = CInt(Math.Ceiling(CDbl(stream.Length) / chunkSize))
        Dim buffer As Byte() = New Byte(chunkSize - 1) {}
        Dim sessionId As String = Nothing
        For idx = 0 To numChunks - 1
            Dim byteRead = stream.Read(buffer, 0, chunkSize)

            Using memStream = New MemoryStream(buffer, 0, byteRead)
                If idx = 0 Then
                    Dim result = Await dbx.Files.UploadSessionStartAsync(False, memStream)
                    sessionId = result.SessionId
                Else
                    Dim cursor = New UploadSessionCursor(sessionId, CULng(CUInt(chunkSize) * CUInt(idx)))

                    If idx = numChunks - 1 Then
                        Dim fileMetadata As FileMetadata = Await dbx.Files.UploadSessionFinishAsync(cursor, New CommitInfo(path), memStream)
                    Else
                        Await dbx.Files.UploadSessionAppendV2Async(cursor, False, memStream)
                    End If
                End If


            End Using
        Next

    End Function
