Convert MDB to CDB

Mdb to cdb file conversion overview

Converting MDB files (Microsoft Access databases) to CDB files (Pocket Access databases) is a highly specialized and legacy task. The .cdb format was primarily used on Windows CE devices and is now largely obsolete.

Limitations of direct conversion

Historically, it was suggested that Microsoft's ActiveSync utility could facilitate data transfer between desktop PCs and Windows CE devices. However, ActiveSync does not provide a direct or reliable method to convert .mdb files to .cdb files. Furthermore, ActiveSync has been discontinued and replaced by Windows Mobile Device Center, which also lacks this functionality.

Recommended approach for migrating data

Because .cdb is a proprietary and outdated format, modern tools rarely support direct conversion from .mdb. The common and practical approach to migrate data from an Access database to a Windows CE device involves exporting the data from Access into a universal format such as CSV or XML, then importing it into the Pocket Access database on the device using appropriate tools or scripts.

Practical options for working with cdb files

• Use Microsoft Access to export tables to CSV or Excel format via File → Export.
• Use third-party tools or custom scripts on the Windows CE device to import data into Pocket Access.
• Explore legacy database synchronization tools designed for Windows CE devices, though these are rare and may require legacy hardware.

summary: There is no straightforward or widely supported method to convert .mdb files directly to .cdb files. Exporting data from Access and importing it into Pocket Access using intermediate formats and device-specific tools remains the best practice.
