.LACCDB File

The laccdb file extension is associated with Microsoft Access, a database management system, part of Microsoft Office Suite, developed by Microsoft Corporation.

Whenever a database in Microsoft Office Access 2007, 2010, 2013, 2016 is opened, the locking mechanisms creates a file with same file name but another file extension.

In case of an opened accdb database, Microsoft Access creates a temporary laccdb file. This file will be automatically deleted when user closes the database.

This mechanism was also used in previous version of Access, which creates ldb files whenever a mdb database is opened.

If for some reason a laccdb file is not deleted when there is no Access database opened, you can safely delete it.

How to open:

These files are not meant to be opened directly.

How to convert:

There is no way how to convert laccdb files to other formats.
