Problem again..... Sometime my officemate told me they cann't go into the system, and a error message appear on screen, **this is not a database file** ( my system is running on DOS - VP2.6 ) I can't open it at command windows too, and the message is same. Did any software to help me to re-bulid the database file. My friend give me a software call 'FileFix' ( very old version ). It can help me to re-build a database file, BUT IT MUST BE NOT INCULED ANY 'MEMO' FIELD. If that file with MEMO field, a message will be appear 'MEMO file is missing' and cann't open that file. HS
