What is an MDB file?

MDB files mostly belong to Access by Microsoft. MDB file extension is associated with the database files created using the desktop relational database application, Microsoft Access.

Main Use: MDB stands for Microsoft DataBase file. It is a proprietary file format developed by Microsoft for storing relational database files associated with one of the Microsoft Office Suite applications, Microsoft Access. The data is stored in these MDB files in a binary container form, using JET (Joint Engine Technology). MDB files are large containers that save the database engine combined with the user data in a single file. In technical terms, MDB files are relational database files consisting of an embedded JET engine.
Other Uses: MDB files are also associated with video editing software, Avid Media Composer. Avid Media Composer uses MDB files to save indexed information concerning the media assets utilized in a video editing project. MDB files are also used to store cache information of the media used in the video editing project which is also indexed for quicker processing. These MDB files are generally automatically by the Avid Media Composer software during the process of video editing and are regenerated if they ever get deleted in the process. MDB file extension is also associated with the presentation creation application, Mediator, and is used to save multimedia information.

How can I open an MDB file?

You need a suitable software like Access to open an MDB file. Without proper software you will receive a Windows message "How do you want to open this file?" or "Windows cannot open this file" or a similar Mac/iPhone/Android alert. If you cannot open your MDB file correctly, try to right-click or long-press the file. Then click "Open with" and choose an application. You can also display a MDB file directly in the browser:. Just drag the file onto this browser window and drop it.

MDB file format details:

Each file has a definite file format, that is, how the stored data is arranged in the file. The first characters in a file identify the file format, for example, HTML files start with the bytes <html>. However, different programs can use the same file extension, and file extensions can be assigned incorrectly. So a detailed analysis of a file is vital in order to determine the format and the associated program. Our evaluation of the MDB files looks like this:

The MDB file extension is quite widespread and is mainly used by one program with a specific format. The two most popular formats are as follows:

85% of all MDB files are associated with Microsoft Jet DB files, which internally utilize the well-known JetDB format. The JetDB is a database format often used by Microsoft Access and Visual Basic programs. JET is short for Joint Engine Technology. These files contain neither text nor words, but only data. A typical file size is 2 MB. The file type is very old but is also used today. The files contain the following words: Standard Jet DB. Such MDB files store data about data, database, backup, found, base, list, sector and projectdb.
2% of all MDB files use the same file format, which have the signature 14 A6 7F FD 23 26 E8 45 32. The contents of these files cannot be read by a human; only a computer program can interpret the data. Most of these files are 520 bytes to 440 KB in size. The files contain the following words: unity, build and buildslave. The following filename is common: UnityEngine.dll.mdb. Such MDB files store data about engine and unity.

All other MDB files (13%) have no uniform format, such as SQL. These files are often connected to engine, unity, access, system, messages, civile or user. Drag & drop your file here to see the file format and a preview of your MDB file!

How to solve problems with MDB files

Associate the MDB file extension with the correct application.
Update your software that should actually open database files. Because only the current version supports the latest MDB file format. Search, therefore, e.g. on the Microsoft manufacturer website after an available Access update.
To make sure that your MDB file is not corrupted or virus-infected, get the file again and scan it with Google's virustotal.com.
