What to Know

This article explains what an XP3 file is, how to open one, and how to convert the file or obtain its internal contents for use in a video game or some other application.

What Is an XP3 File?

A file with the XP3 file extension is a package file used by KiriKiri, a scripting engine. The XP3 file is often used with visual novels or for storing video game resources.

Inside the file might be images, audio, text, or any other resource that would be useful during gameplay or for a visual representation of a book. These files are stored in the XP3 file like an archive, similar to ZIP files.

XP3 is sometimes used as an abbreviation for Windows XP's service pack version 3. However, files that use this extension have nothing to do with any operating system in particular.

How to Open an XP3 File

KiriKiri Package files can be opened with KiriKiri Tools.

If the file doesn't open with that program, try using a free file extractor to extract the contents out of it. You'll most likely see an EXE file that you can run like a regular application. Software like 7-Zip or PeaZip should be able to open an XP3 file in this way.

If a file unzip tool doesn't help, try CrassGUI. There are instructions on that download page that explain how to open the XP3 file.

In all of these examples, the end result might be that you have to copy the extracted files into a certain folder. For example, if the XP3 file is used with a particular video game, you might have to extract files out of it and then copy them to the game's installation folder in order for the game to use them.

How to Convert an XP3 File

More popular file types can be converted to other file formats with a free file converter. For example, a file converter can be used to convert PDF files to DOCX. But we're not aware of any that work with XP3 files.

However, one thing you might try is to use the KiriKiri Tools program mentioned above. If it's possible with that program, the option for converting the file might be in a File > Save As menu or an Export menu option.

Still Can't Open It?

If your file won't open at this point, you might be misreading the file extension. Confusing another file extension for XP3 is easy considering that lots of other files use similar letters and numbers in their extensions.

For example, XP3 shares some of the same letters as ZXP, XPD, and XPI, but that doesn't mean those file formats have anything to do with each other. P3 is another example where the file extension is reserved mainly for Primavera P3 Project files

If you can't open your file, double-check that you're reading the extension correctly and not confusing one of those files for an XP3 file.
