The BDB file extension is associated with QuickBooks, business accounting software developed and marketed by Intuit. QuickBooks Timer uses BDB files to back up its timer data, including recorded time entries and related timer records.
A BDB file is a backup of QuickBooks Timer data, not the main QuickBooks company file. It is intended to be restored through compatible QuickBooks software or QuickBooks Timer and used with the accounting data to which the time records belong.
The format is associated with QuickBooks for Microsoft Windows and QuickBooks for Mac. Compatibility can depend on the QuickBooks release and the version that created the backup. BDB is a legacy QuickBooks Timer backup format and is normally encountered with older QuickBooks installations.
Open the file with the QuickBooks installation or QuickBooks Timer version that created it, and use the program's backup-restore function. QuickBooks for Windows and QuickBooks for Mac are separate product lines, so use the matching platform and a compatible release where possible.
Do not expect a BDB file to open as a regular document or database in another application.
A BDB file is a backup rather than an interchange document, so it normally cannot be converted directly with a general-purpose converter.
Restore it in a compatible QuickBooks installation first. After restoration, use QuickBooks' own reporting or export features to save the recovered data in any formats supported by that installation.
