I have a similar data base on another machine and so I will reenter the dat into this data base. I suspect that my very old lenova laptops need to be replaced.

My Google searches for command-line ways to export the contents of a LibreOffice Base file turned up instructions for how to do it from within LibreOffice, which won't be useful for you since you can't open the file. I've often used the command-line to export the contents of LibreOffice Calc files to CSV. A Google search and a climb through LibreOffice's man page didn't reveal whether the same can be done with Base files, but it's worth a try. Maybe either or both of these would export the data to an .sqlite or a .db file if you open a terminal window in the same directory as your database file and replace example.odb with the name of the database file: libreoffice --convert-to sqlite example.odb ...or... libreoffice --convert-to db example.odb If either of them work, you could then open the resulting exported file with Base or import it into Base. If neither of them work, you could try accessing the database from Python or your favorite language to retrieve the data and then write it to a .db or .sqlite file that you could either open with Base or import into Base afterwards. I can provide some clumsy help with accessing the database from Python or others in here who are more advanced in Python could probably whip up some efficient code to get the job done. </pre> </blockquote> </body> </html>
