I'm sorry but i found that the UDF_FILE.DLL is a dll for interbase
by David Revill that is downloadable from ibphoenix
(http://www.ibphoenix.com/main.nfs?a=ibphoenix&page=ibp_udf_libs)
and maybe is not full compatible with firebird.

Anyway if anybody is using that dll and knows a workaround please
let me know.

Thanks for your response
