>>>A client of mine reported a weird problem.
>>>The scenario:
>>>- Application and data are located on a mapped drive Z:\ which is a Nas (i.e. 192.168.1.20) accessed by three computers.
>>>- Data are like: TableMaster.dbf (plus TableMaster.cdx), TableDetail.dbf (plus TableDetail.cdx).
>>>After an insert, through the applicazion form, data got corrupted like that:
>>>TableMaster.dbf became 5EFC00K.TMP
>>>TableDetail.dbf became 5EFC00L.TMP
>>>While CDXs stayed with the correct name: TableMaster.cdx + TableDetail.cdx.
>>>To solve, I had to manually rename
>>>5EFC00K.TMP -> TableMaster.dbf
>>>5EFC00L.TMP -> TableDetail.dbf
>>>Besides, overwrite CDXs with empty ones, then reindex.
>>>The question: which may be the explanation for such a problem?
>>>How to prevent from occourring again?
>>>TIA.
