What is an .LACCDB file?

.LACCDB is Microsoft Access database lock

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.

These files are not meant to be opened directly.

How to convert:

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