>Hi all, it´s me again with the same problem with the *.ntx file. I have some tables made in clipper 5.2 and they´re a "free tables" apparently, and I say this because there´s a file with the *.ntx extension, it´s a index file, and I guess that in these file is located the information about the relations and the integrity reference, I don´t know ´cause I even can´t open this file.

Yuseff,
In CLIPPER there is no such term as Integrity reference. You must program all by yourself. Also when you delete some records, pack the table, change values of the fields which are involved in some of the CLIPPER indexes, CLIPPER index not match the table anymore, you must reindex the table in CLIPPER application. Why you open CLIPPER table with VFP? Also CLIPPER tables as like FOX2 tables, they are not compatible with VFP tables, if you make some changes sometime you even can't open these tables in CLIPPER.
