What is a GTP file?

GTP files mostly belong to Altium Designer. GTP files can mean different things based on the software that created them.
For some, a GTP file holds the PCB top paste mask data used in printed circuit board design. These files define where solder paste is applied and are opened in design tools such as Altium Designer or KiCad. More details are available at Altium Designer.
In other cases, GTP files store Guitar Pro tablature information. They keep guitar notes and tab data, and you can open them with the Guitar Pro application. See Guitar Pro for further information.
Another use for these files is as a Game Texture Package in titles like IL-2 Sturmovik and Mount & Blade II: Bannerlord. They hold texture and image data for game environments. Visit IL-2 Sturmovik or Bannerlord for more on this application.
A smaller group of GTP files also uses a plist structure to work as a Garmin Trip Planner or GPS track file. Such files may be handled by software that supports plist formats. For example, check details at Apple GarageBand.
  • Review the file’s header to identify its origin.
  • Open the file with the correct software.
  • Backup the file before making changes.
  • How to open GTP files

    You need a suitable software like Altium Designer to open a GTP file. Without proper software you will receive a Windows message "How do you want to open this file?" or "Windows cannot open this file" or a similar Mac/iPhone/Android alert. If you cannot open your GTP file correctly, try to right-click or long-press the file. Then click "Open with" and choose an application. You can also display a GTP file directly in the browser:. Just drag the file onto this browser window and drop it.
