File transfer applications can transfer information in addition to, and to accompany, the information in the transferred files. The sending application can transfer the information as part of the arbitrary data in the lpTag parameter of the xfSend and xfConnectAndSend function calls. The receiving application can use the xfGetStatusLong function call to retrieve this information.
The information could instruct a specific word-processing application where to position a cursor after opening the transferred file. The information could also be the sole information transferred in the connection, with no accompanying files. This provides for a crude, interprocess connection between computers.
