A PT3 file belongs to the device-support files used by Harvard Graphics. The driver enables the software to communicate with a supported output device, such as a printer or plotter, rather than storing a presentation, chart, or other user document.
Harvard Graphics was presentation software available for MS-DOS and Microsoft Windows. The Harvard Graphics product line was later acquired by Serif. This PT3 file is associated with Harvard Graphics ChartXL for Microsoft Windows.
PT3 is a proprietary, application-specific format intended for use with compatible Harvard Graphics software.
A PT3 file is not normally opened directly. Install and run a compatible version of Harvard Graphics ChartXL for Microsoft Windows, then select the file through the application's device or printer setup.
There is no general-purpose PT3 viewer. Current versions of Windows may not run this older software without an appropriate legacy environment.
A PT3 file is a device driver, not a document, so it cannot usually be converted meaningfully to another file format. Keep it with the compatible Harvard Graphics installation if the original output device is still required.
To use a different device, install a driver supported by the application or recreate the document in a current program and export it using that program's available output options.
