Files that contain the file extension LACCDB are related to Microsoft Access, which is a spreadsheet and database application that is part of the Microsoft Office Professional productivity suite of applications. LACCDB files are a temporary database lock file commonly associated with the 2007 version of Microsoft Access.
LACCDB files contain data and information that includes text, mathematical calculations, formulas, objects, layouts, charts, graphs, reports and other elements that are used with database applications. Whenever you open a file in Microsoft Access, another file is created with the same file name except that it uses the LACCDB extension. The file is created with the locking feature which is included in the 2007 and 2010 version of Microsoft Access.
The files that you open in Access are considered to be part of the ACCDB database, which is a fairly recent standard set by Microsoft for the newer versions of the Access application. ACCDB files replace the earlier MDB file extension, which is where the temporary files created with the opened file obtain the extension of LACCDB.
Once you close ACCDB files, the LACCDB file is automatically deleted. If for any reason the LACCDB file is still present once you close the Access database, it is safe to right click on the file and then choose Delete from the drop-down menu.
How to Open LACCDB Files
LACCDB file extensions are meant to be used with the program they are associated with, which can be Microsoft Access or Microsoft Excel. If you use Windows, you can open LACCDB files with Microsoft Access, which is available with Microsoft Office Professional or the program can be used as a standalone application. Access uses the Jet Database Engine, which is a database format exclusive to Access and capable of supporting databases imported from other applications.
You can also open LACCDB files using Microsoft Excel, which is a spreadsheet application that is part of any version of Microsoft Office. There have been instances where the file will save as an LACCDB as opposed to an ACCDB file extension, which can make the file difficult to open with Excel and other programs. In this case, it is necessary to convert the file back to the ACCDB extension to allow it to be opened using Access, Excel, or another database application.
Another option is to convert the LACCDB back to the ACCDB format and then proceed to convert the AACDB file to another extension such as XLS. If you convert the file to an XLS extension, you can open it using Microsoft Excel or OpenOffice Spreadsheet, which is part of the OpenOffice Suite of productivity applications. OpenOffice is available as a free download on the OpenOffice.org website.
To convert files to another file extension, you can use a file conversion program. There are a variety of file conversion programs available as a free download on websites such as CNET and Softpedia which will convert the files for you.
