If (and only if) your source is a MS Works database, a tutorial and demo - for transfering the data from a Works database to OOo Base - can be downloaded from http://db.tt/zvzHylN0
. The process does, however, require that you initially have a MS Works program to open the source database. I have found the process to be fairly reliable in avoidance of hidden errors (particularly in the case of large database files), but its detailed requirements are such that it is not suitable for the wholesale transfer of a significant number of Works .wdb files all at one time.
When this issue has been resolved, it would help other users of the forum if you add the word - [Solved] - to the Subject line of your 1st post (edit button top right).
