What is the HP4 file format?
A file with the .HP4 extension is a file known as Harpoon Classic game data. It belongs to the Game Files category.
The reliable way to open a .HP4 file is with software that recognises this exact format, rather than guessing from the file name. If you are not sure what created a file, our file identifier can read its first bytes and name the real format, even when the file has been renamed.
We are still gathering the list of programs that open .HP4 files. A fully verified, hand-written description of this format is being prepared; until then, the details on this page are drawn directly from our database.
