Yep, and this is exactly why you don't store sensitive data in an Access database. There is simply no way to protect it reliably.

What should I do to protect Ms-Access (.MDB ) file? Is there any way through which I can hide database file.


No, there isn't. Since Access is a file-based database, the .MDB file must be visible to the user using your application. This means he'she must have Read and Write access to the .MDB file. You can turn on the Hidden file attribute, but this is pathetically easy to defeat.

You can try to encrypt some of the database in the database, but you have HUGE performance problems and usability issues.

The only way to secure sensitive data is to use a real database engine, like SQL Server or Oracle. The security is MUCH better and easier to control.
