Open CDB File

The CDB extension files can acquire various applications depending on their format, some of them are as follows:


In this first case, the CDB files are a Symbian contacts and calendar database.

Symbian is a discontinued mobile operating system and computing platform designed for smartphones.

It was originally developed as a proprietary software operating system for personal digital assistants in 1998 by the Symbian Ltd consortium.

Symbian OS comes standard on Nokia phones.

Thus, the CBD contains the phonebook contacts, including names, addresses and phone numbers.

The CBD, too, is used to back up and sync contacts between a computer and a Symbian OS device.

CDB files are typically found under the name 'CONTACTS' followed by the CDB extension.

They can be converted to vCard files with the VCF extension, using Nokisoft Noki.


Similar to the previous case, here, the CDB is a database file created by CardScan, a program that allows users to organize and sync their contacts between desktop computers and mobile devices.

The CardScan software is no longer supported and is not being developed.

In this case, the CDB file contains all contacts stored in a proprietary format.

CDB files can be synced, exported, or imported from Microsoft Outlook, iPhones, Blackberry handheld devices, Windows mobile devices, and many other devices and programs.

CardScan is available in Personal, Executive, Team and At Your Service editions.

Pocket Access

Similar to the cases above, the CDB file is a database file created by Pocket Access, a relational database program similar to regular Microsoft Access, but with reduced complexity for Pocket PC mobile devices.

A Pocket PC is a type of personal digital assistant (PDA) running the Windows Mobile or Windows Embedded Compact operating system that has some of the capabilities of modern desktop PCs.

The Pocket PC name was changed to Windows Mobile in 2007, however it is no longer developed and discontinued.

The CDB file can contain relational database schemas, forms, and reports, and is used to store Access data on mobile devices.

Software to open and work with a CDB file

Despite the fact that the functionality of a CDB file is similar for all the formats reflected here, it is important to take care of this format, since using the wrong application can cause damage to the file.

  • CardScan (Discontinued)
