File Extension QBB

The QBB file extension is associated with QuickBooks, which is a software application designed for working with financial data. QuickBooks is developed by Intuit, and the extension is responsible for backing up financial data for the software application.

Since QBB files are backup file types, they contain an exact copy of data related to accounting records and financial transactions which can easily be restored in the event of data loss or when something happens to the primary file which is identified with the QBW file extension. The data typically contains templates, financial information, letters, images, and other content used with database style applications.

QBB files are typically created using QuickBooks for Windows, but they can also be created using QuickBooks for Mac. If the files are created on a Mac PC, there is a feature in QuickBooks which allows you to backup QBB files to QuickBooks for Windows.

How to Open QBB Files

To open a QBB file, try double clicking on the file to see if it automatically opens in a default application. If you have QuickBooks installed on your PC, you should be able to access the QBB file using this method.

In Windows you can open QBB files using QuickBooks for Windows or by importing the QBB file into another spreadsheet application such as Microsoft Excel or OpenOffice Spreadsheet. Excel is part of the Microsoft Office suite of applications, and Open Office Spreadsheet is available as a free download from Once you have the appropriate program installed, simply click on File and then choose Import from the drop-down menu. Browse for the QBB file you want to open and then click on Import. This should open the QBB file in the spreadsheet.

For Mac OS X, you can use QuickBooks for Mac or by using Microsoft Excel for Mac, OpenOffice Spreadsheet, Apple Numbers, or Mesa. You can also choose to convert the QBB file to another format using a conversion program capable of converting financial data to another format.

It is also a good idea to make a backup of a backup. For example, if you have a QBB file which backs up data for a QBW primary file in QuickBooks, you may want to create a second backup file and then place it in a separate storage location.

QuickBooks files are known to become corrupt. If the primary QBW file and the QBB file both become corrupt, this leaves you with another option for accessing the data in the file without having to resort to a file recovery program which may or may not work.
