The Fileshare Server can pass I/O requests to a program specified by you, rather than by the Micro Focus File Handler, as long as the program that you specify conforms to the call interface used by the File Handler.
Note: If you are handling files using DXFORMATs 17 and 21, transaction processing capabilities are not supported.
You do not need to change the configuration of the Fileshare Client to use the Virtual File Handler Interface.
