In some projects, I can't do without Visual FoxPro. My problem right now is this: I have an unsuccessful .dbf with important data, and no matter what methods I tried, I could not access the database. I need to extract data or open it.

Have you tried exporting to Microsoft Excel ? Subsequently, you can save as CSV and import it to some other database format. However, please enlighten me. Why can't you do without Visual FoxPro in some projects ? I mean for a project that was discontinued about 10 years ago. There has to be other options by now, right ?

Try opening the .dbf file in Excel or other program that supports opening the .dbf format.
Once opened in Excel you should be able to view the file, delete any "bad data", and resave to a new name (with the .dbf extension).
Also possible to create a new table with the structure of the old table, append records from the old to the new. May salvage records until the corruption is encountered.
