This property is automatically set every time you perform a WRQ/Reflection transfer from the dialog box and the value becomes the default for the next transfer. This property has no effect on programmatic transfers; if you don't explicitly specify a transfer type with WRQSendFile or WRQReceiveFile, the default is always ASCII.

This property is relevant only for transfers that use the WRQ/Reflection protocol.

The default value is TransferTypeOption.ASCII.

• Specifies ASCII file transfer. Reflection applies the ASCII File Translation options (as specified on the Translation tab in the File Transfer Setup dialog box) to the data in the file as it is transferred.
• Specifies binary file transfer. Data in the file is not translated as it is transferred.
• File transfer type is determined by the file extension. Use these properties to determine which file extensions are linked to which transfer type: TransferAutoDetectDefaultType; TransferAutoDetectASCIIExtensionList; TransferAutoDetectBinaryExtensionList; TransferAutoDetectImageLabelsExtensionList; and TransferAutoDetectScanExtensionList.
• Host to host Image/Labels transfer (TransferTypeOption.Labels is a valid synonym).
