What is a .CPD file?
The file extension .CPD stands for Compressed PhotoDefiner Image File. It is primarily associated with the software Adobe RoboHelp, which is used to create help documentation for Windows applications. The .CPD file is a type of database file that is part of a larger RoboHelp project, usually saved with the .XPJ file extension. This file contains cached information which helps in managing the project efficiently.
It is important to note that .CPD files are not meant to be opened or edited manually. Doing so can corrupt the file or cause errors in the RoboHelp project. These files are automatically managed by Adobe RoboHelp.
In terms of technical details, the .CPD file uses a type of lossless compression which can also be applied to re-compress PNG files. This means that the compression keeps all the original data intact (lossless) and can reduce the file size without losing any quality.
To open a .CPD file, you should use Adobe RoboHelp, as it is specifically designed to handle and manage these files as part of its project management system. Other programs might not be able to open this file type correctly.
