Standard and Advanced Upload Modes (Learn more)

The control can work in either Standard or Advanced upload mode. In Standard mode, a file is sent to the server in one request and is cached in server memory. In Advanced mode, a file is sent to the server in small packets (one by one) and is saved in a temporary file in a specific server folder.
