Unexpected error 35012

[robertJe]

Here is my problem: Microsoft Access crashes frequently when I am opening mdb extension file. The 'Unexpected error 35012' message pops up.
Can anyone explain whats happening and provide a solution? How to open the file?

Manually compact and repair a database

In addition to or instead of using the Compact on Close database option, you can manually run the Compact and Repair Database command. You can run the command when you have a database open, and you can run the command on a database that is not open. You can also create a desktop shortcut that runs the Compact and Repair Database command on a particular database file.

Compact and repair a database that you have open

Note: If other users are also currently using the database file, you cannot perform a compact and repair operation.

On the File tab, click Info, and then click Compact and Repair Database.
