What is a ACCDB file?
Files with the .ACCDB extension contain databases, namely data distributed in tables and fields coupled with SQL queries and forms, saved in a format unique to the Microsoft Access software, versions 2007 and newer.
ACCDB files are a replacement for MDB files, with functionality extended with the option to store attachments or binary data, encrypting data, as well as integrate with other programs from the Microsoft Office suite, such as MS Outlook or Sharepoint, which was previously not permitted due to the possibility of malware infection.

More information about ACCDB file
ACCDB file is a database file format used by default by Microsoft Access 2007 and later. Data stored in ACCDB file is organized into tables and fields that can include SQL queries, custom forms, and other data specific to given database software.
ACCDB format as the successor to MDB format
ACCDB format is the successor to older format MDB, which was considered standard Access format before the release of Access 2007. New format offered some additional features, such as support for multivalue files, data macros, database encryption, or ability to store atachments and binary data. Along with ACCDB format developers introduced solutions such as integration with other Microsoft products (Outlook and SharePoint) not possible before due to security vulnerabilities present in earlier format. The newer format, however, doesn’t support some of the older functions, including replication and user-level security policy.
ACCDB and additional LACCDB file
During work with ACCDB file in MS Access a database lock file (LACCDB) is automatically generated in the same folder as the ACCDB file. Lock files prevent any attempts to modify the original database file. Locking features are especially useful if more users are working with the same file simultaneously.
How to open ACCDB files
If you cannot open the ACCDB file on your computer - there may be several reasons. The first and most important reason (the most common) is the lack of a suitable software that supports ACCDB among those that are installed on your device.
A very simple way to solve this problem is to find and download the appropriate application. The first part of the task has already been done – the software supporting the ACCDB file can be found in the table. Now just download and install the appropriate application.
Possible problems with the ACCDB format files
The inability to open and operate the ACCDB file does not necessarily mean that you do not have an appropriate software installed on your computer. There may be other problems that also block our ability to operate the Microsoft Access 2007/2010 Database Format file. Below is a list of possible problems.
- Corruption of a ACCDB file which is being opened
- Incorrect links to the ACCDB file in registry entries.
- Accidental deletion of the description of the ACCDB from the Windows registry
- Incomplete installation of an application that supports the ACCDB format
- The ACCDB file which is being opened is infected with an undesirable malware.
- The computer does not have enough hardware resources to cope with the opening of the ACCDB file.
- Drivers of equipment used by the computer to open a ACCDB file are out of date.
If you are sure that all of these reasons do not exist in your case (or have already been eliminated), the ACCDB file should operate with your programs without any problem. If the problem with the ACCDB file has not been solved, it may be due to the fact that in this case there is also another rare problem with the ACCDB file. In this case, the only you can do is to ask for assistance of a professional staff.

How to associate the file with an installed software?
If you want to associate a file with a new program (e.g. my-file.ACCDB) you have two ways to do it. The first and the easiest one is to right-click on the selected ACCDB file. From the drop-down menu select "Choose default program", then click "Browse" and find the desired program. The whole operation must be confirmed by clicking OK. The second and more difficult to do is associate the ACCDB file extension to the corresponding software in the Windows Registry.
Is there one way to open unknown files?
Many files contain only simple text data. It is possible that while opening unknown files (e.g. ACCDB) with a simple text editor like Windows Notepad will allow us to see some of the data encoded in the file. This method allows you to preview the contents of many files, but probably not in such a structure as a program dedicated to support them.
