What is a CPD file?

Database file created by RoboHelp, a program used for authoring Windows help documentation; stored as part of a RoboHelp project (.XPJ) and contains cached information for the project; should not be opened or edited manually.

More Information

CPD files are saved in a Microsoft Access database (.MDB or .ACCDB) format and can be opened with Access. However, this is not recommended since RoboHelp uses the data in the background for caching and it could cause the program to malfunction.

NOTE: Your project cache can be cleared each time you open a help project by choosing the "Clear project cache (.cpd) before opening any project" option in the General tab in the application preferences.
