Notes about the PPC file extension:
Incorrect file associations could be the result of underlying issues within your PC system. As such it is highly recommended to scan your PC for invalid registry entries, unused processes and other unfavourable system settings to identify slowdown issues.
The PPC file type is primarily associated with 'Breeze' by Macromedia. When recording audio and slide synchronization, the Macromedia Breeze Plug-in for PowerPoint creates a PPC file. The PPC file contains the audio and syncing information for the presentation. This file is automatically created and managed by the Macromedia Breeze Plug-in for PowerPoint. If the PPC file is deleted, or if the PowerPoint presentation is moved to another machine and the PPC file is not included, the audio and syncing will be lost for the presentation.
