Different File Formats of Microsoft Access

MS Access works on two file extensions:

  • .mdb
  • .accdb

Before the introduction of .accdb files in Access 2007, file format used was .mdb. There are many editions of MDB file extension. Users can still access the .mdb files as they are operable on Access 2003, 2002, 2000. But, the users are restricted to take the advantages of .accdb files. In contrary to it, there are few features that can be accessed by only MDB files. All the features of MDB file extensions that are not present in ACCDB files are jotted below:

  • It provides Mixed Version Environment. It means that the ACCDB file extension cannot be opened or linked to the earlier versions of the MS Access below 2007. If an employee of an organization who comprises of earlier MS Access version he/she must opt for the MDB file extension. As, the MDB files would be of use in such case. Users can even use Access or Web Database in web browser irrespective of the fact whether MS Access is pre-installed in the system or not.
  • The Database Replication is also supported by Microsoft Access MDB files. But it is totally dissimilar to the ACCDB files in Access arena. If MS Access uses the Replication feature, users need to recreate solution to use ACCDB files.
  • Provides User Level Security while working in MS Access Arena. The ACCDB file does not support the user-level security feature. This feature provides the users with a way to help in what they want to see. The user level security is not effective in the data security. The security method has been eliminated and can easily compromised. In many cases, the user-level security improves the usability as it keeps things simple for the users. In case, a user has no business reason to make use of a particular form, then the users can hide the form. If a user needs an Access solution that is dependent on the user-level security to improve the usability then they can make use of the .mdb files without any hassle.

ACCDB file format is MS Access is starting from Access 2007. The .accdb file format supports a lot of newer features like attachments and calculated fields. In many circumstances, the ACCDB file format is considered as the right choice because of the efficient features:

All of the features of .accdb files are jotted below:

  • Applications and Web databases using the Access Services: By giving the proper server resource, users can publish an ACCDB file to Web irrespective of some compatibility restrictions. The write-up provides the users with two ways through which it can be performed.
  1. Access Database
  2. Web Database

The Access Applications are newer form of the database. This app runs entirely in cloud. MS Access itself serves as a designing tool for many applications. Many applications take the advantage of a latest SQL Server and the SharePoint technology. The Web database released in Access in 2010 version though it served much similar functionality but does not support the SQL Server. After publishing an application or a web database, the database is always present on the Server. Users can easily open the database as an .accdb file for making changes in design. The web database or application runs on browser without the Access.

  • The Multivalued field is a lookup field that makes the users stores more than a single value per record. For instance, if a user wants to assign many users a task, it can be done in ACCDB file as users can create a multi-valued field to store the name of employees that have been assigned the task. Users can even select the value from the table and list of the values. The Multi-valued fields makes easy for the users to select and store more than one choice without using create more advance database design. The Multi-valued fields are important for the process of integration with SharePoint as SharePoint list even supports the multi-valued fields.
  • The Attachment Data Type enables the users to easily store the documents and the binary files in the database keeping the file under the size of 2 GB. The attachments present are automatically compressed. The record possesses multiple attachments but addition of only one field per table is required.
  • The ACCDB files have a great Interaction with the SharePoint and MS Outlook. As these files easily supports the security requirements that an .mdb file does not support.
  • The .accdb files provide users with the improved encryption. Users can even select a set of a database password and encrypt the contents of the database. The MS Access ACCDB files use Windows Crypto API by default to encrypt data.

These files often generate confusion among users as both of the main files and LDB files are generated together. So, the deletion becomes necessary because sometimes excessive LDB files can even lead to MS Access database corruption.

Sometimes, corruption even occurs due to the excessive files in MS Access. Then users should create a new file and export the data from the corrupted databases. Mentioned below are few points through which the users can easily perform the same.

The Jet Compact Software i.e., JETCOMP.exe is basically treated as a Stand-alone utility that is associated with the MS jet database Engine 3.x and 4.x. The program can be run in conjunction with the MS jet database engine 3.x & 4.x in case of recovering the corrupt databases. Users can even run the MS Access Compact software for repairing the corrupted Access databases. The Jetcomp.exe is capable of recovering the databases that simple programs cannot perform. The basic cause of this is that the tool is capable of open and closing a database before compacting it. In many of the cases, the utilities are able to reopen databases. The Compact option is unable to go to next level as it is preventing the restoration of database. Jetcomp.exe does not open and close the database before the process of compacting. Henceforth, it is able to recover the database that other software cannot perform.

Before the users continue with the Compact and repair built-in tool, they should jot down the following necessary instructions:

  • Always make a backup of the files.
  • Compact and Repair the databases automatically.
  • Note down the System recovery error table.
  • Get the access to database to make use of Compact and Repair database command.
  • Acquire the sufficient Permissions to run compact and repair function.

The inbuilt utility functions in two ways:

  1. The database that are opened by users:

  • Firstly, Start MS Access but do not try to open the database files in it
  • Point towards info ⇒ Click Compact and Repair Database
  • In the dialog box of database to compact form, navigate and double click on the databases to be repaired

Note: In this case, if any other user is accessing the database files, then users can perform the compact and repair operation. While running the compact and repair option other users cannot access the database files.
