Have you encountered a problem with a ACCDB 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 ACCDB file here. In the further part of this page we have added a list of programs that should open your ACCDB file. It is enough you choose a proper application for your operating system, download and install it.


The ACCDB file extension identifies database files of the Microsoft Access database application. These files include data organized in tables and fields, forms, SQL queries, and other data. Access is a proprietary database management system for managing data in databases and developing database applications.

The ACCDB format was introduced by Microsoft with the 2007 version, replacing the old mdb format. The new format offers an extended range of functions. These include database encryption, multi-value fields, the ability to save file attachments and other binary data, and integration with MS Outlook and MS SharePoint.

In addition to Access and a few other database applications, the Microsoft Visual Studio programming environment can handle ACCDB files. In order to read OpenOffice ACCDB files, select 'Connect to an existing database' in the start dialog and set 'Microsoft Access 2007' in the drop-down box underneath. After clicking on 'next' one comes to the file selection, in which one can select also ACCDB files. How reliable the import is and whether this functionality also exists under Linux and Windows, could not be tested so far.

FileMaker Pro requires the FmPro Migrator.

How to open a ACCDB file? Advice and guidance

Absolutely most often appearing reason that prevents you from opening the ACCDB 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 ACCDB 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 ACCDB files. At this point we are looking for disk space where the application was installed in and we can link it with a ACCDB file. Since then, our operating system will use the selected program to support all ACCDB files.

Other issues

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

- verify that the ACCDB 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 ACCDB 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.
