📌 Mostly, the .CDB format composition may be associated with the database files generated, opened, and built by mobile devices on the basement of Symbian OS mobile architecture, such as Nokia smartphones. In detail, the .CDB layout includes phonebook contacts, taking into account phone numbers, addresses, and names. Therefore, the .CDB specification is applied to synchronize and backup contacts between a Symbian OS device and a computer. .CDB formatted file entries are normally encountered with the contacts.cdb entitlement. Correspondingly, they can be converted into vCard .VCF composition with the assistance of Nokisoft Noki program toolkit.
📌 In certain occasions, the pinpoint .CDB variation may correlate with a database file entry generated and opened up by CardScan, a package that provides facilities for the users to synchronize, arrange, and organize their contacts between mobile devices and desktop computer stations. Precisely, the noted .CDB schema node includes all contacts stored in a proprietary definition. .CDB file patterns can be imported to, exported from, or synchronized with Windows mobile devices, Blackberry handhelds, iPhones, Microsoft Outlook, and various other programs and devices. CardScan project is distributed, shared and available in At Your Service, Team, Executive, and Personal edition sets.
📌 Extensively, the .CDB format foundation may rely on the database file object composed by Pocket Access, a relational database engine on the logic and mechanics pretty close to Microsoft Access, but equipped with more facilitated hierarchy and principles for Pocket PC mobile devices. Accurately, the noted .CDB arrangement may contain designated relational database reports, forms, and schemas. In practice, the following .CDB file layout is utilized for storing assigned Access data on mobile gadgets and devices. In the meantime, the .CDB file constitution can be flawlessly and successfully converted to .MDB representation with the interference of Microsoft ActiveSync suite.
How to open an .CDB file?
📌 In the case when the target .CDB extension composition references database sources built by Symbian OS smartphones, the corresponding .CDB file contents can be monitored, opened, and comprehended by Nokia PC Suite and Nokisoft Noki packages, adapted for practical necessities within Windows and macOS environments. As an exception, the peculiar .CDB file entity can be uncovered and sustained by CardScan and CardScan AutoSync bundles, not available for direct download from the trusted developer’s portal in accordance with the project expiry status. Finally, the properly noted item category can be researched and analyzed by Microsoft ActiveSync web-service, which also may appear eligible for converting actual .CDB-covered items into .MDB constitution, more common among database developers and analysts.
