Have you encountered a problem with a HPG file? Don’t you know which program opens a file with this extension? You will find all the information you need about working with a HPG file here. In the further part of this page we have added a list of programs that should open your HPG file. It is enough you choose a proper application for your operating system, download and install it.


The HPG suffix identifies files that contain data in the page description and plotter control language HP-GL (HPGL) in an ASCII text. Hewlett-Packard developed this language for the control of pen plotters, it was subsequently adopted by other manufacturers. Inkjet (inkjet) and laser printers can also be controlled with HP-GL.

HP-GL files are also used for the exchange of vector data. Many CAD programs support export in HP-GL format. However, they can also be generated by printing in a file and setting a corresponding printer / plotter eg The HP750C. However, this method also carries risks because full compatibility can not be guaranteed.

These files also use the extensions hpgl, plt, pgl, hgl and less prn. Changing the extension may be useful unless the file can be opened directly.

How to open a HPG file? Advice and guidance

Absolutely most often appearing reason that prevents you from opening the HPG file is the lack of a proper application to support it in your operating system. It is notably the first thing you need to address. When one of the programs to support a HPG file from the list is already installed, you can try to rerun the file. The system should display a message asking you to choose a primary application to support HPG files. At this point we are looking for disk space where the application was installed in and we can link it with a HPG file. Since then, our operating system will use the selected program to support all HPG files.

Other issues

Despite the described problem with HPG there may be many more problems. If the existing operations were not effective, get involved with the following matters:

- verify that the HPG file is not damaged and that it has been downloaded or copied in whole
- verify that the file has a file extension that has not been intentionally changed (for example, if it do not contain other information than its extension suggests)
- make sure again whether the HPG file type is linked in the operating system with a proper program
- make sure that the file is not infected with a virus and you have up to date software and drivers.
