Have you encountered a problem with a MDB file? Don’t you know which program opens a file with this extension? You will find all the information you need about working with a MDB file here. In the further part of this page we have added a list of programs that should open your MDB file. It is enough you choose a proper application for your operating system, download and install it.


An MDB file is a database file created using Microsoft Access or a compatible software or interface. Although the Microsoft Access Database (database) format is a proprietary format, Microsoft has since made it partially accessible. Since Access 2007 the extension accdb is used.

Microsoft Access is a relational database application that is widely used worldwide. Access is part of the Microsoft Office suite, but only available for Windows. However, there are other database programs and numerous applications that can handle or use MDB files because MDB databases can also be accessed and generated using the Microsoft Visual Studio programming applications. (eg with Visual C #)

An MDB database file contains not only the pure data, but also the structure (tables and fields), input masks, queries, and database security settings. Mbd files can also contain links to files of other Microsoft Office applications (eg Excel spreadsheets). Unfortunately there are quite a few versions of the MDB format that are not all compatible with each other. Therefore, a converter must be used for import problems.

When reading into foreign programs or converting an MDB file, in most cases "only" the data is obtained. On the other contents like the input masks and so on one must do without normally.

On Mac OS systems, one can use 'actual Tech Access Databases' to set up an interface for accessing other applications on Access databases. (eg for FileMaker)

How to open a MDB file? Advice and guidance

Absolutely most often appearing reason that prevents you from opening the MDB file is the lack of a proper application to support it in your operating system. It is notably the first thing you need to address. When one of the programs to support a MDB file from the list is already installed, you can try to rerun the file. The system should display a message asking you to choose a primary application to support MDB files. At this point we are looking for disk space where the application was installed in and we can link it with a MDB file. Since then, our operating system will use the selected program to support all MDB files.

Other issues

Despite the described problem with MDB there may be many more problems. If the existing operations were not effective, get involved with the following matters:

- verify that the MDB file is not damaged and that it has been downloaded or copied in whole
- verify that the file has a file extension that has not been intentionally changed (for example, if it do not contain other information than its extension suggests)
- make sure again whether the MDB file type is linked in the operating system with a proper program
- make sure that the file is not infected with a virus and you have up to date software and drivers.
