CommDb, the Communications database for Symbian OS, provides a system-wide storage for communications-related settings. S60 SDKs provide a pair of command-line tools, CED and CEDDUMP, which can be used for analysing and configuring CommDb settings.

The ability to view all information in the database (when running on the emulator) is useful for applications that access and modify the CommDb. With CEDDUMP, the information stored in the CommDb can be exported into a plain-text file, making it easy to verify any changes made. However, the ceddump.exe included in S60 SDKs provides only a restricted view of CommDb contents, excluding any S60-specific tables.


A version of the CEDDUMP tool capable of exporting all CommDb settings is available at File:Ceddump .zip.

Extract the zip file to the \epoc32\tools directory under the SDK installation path. The original ceddump.exe included is not overwritten; the new version of the tool is named ceddump_.exe.

The tool is compatible with all S60 3rd Edition and S60 5th Edition SDKs.
