What Is a RAF File?

A RAF File is easier to understand when the core ideas are explained in practical terms. This guide covers what it means, how it works, why it matters, and the main details you should know.

What Is a RAF File?

A file with the RAF file extension is an uncompressed RAW image captured by a Fujifilm digital camera. RAF files can include JPG images of the same image captured by the camera.

This file extension is also used for Riot archive files for the League of Legends video game and is displayed alongside RAF.DAT files. DAT files store the actual data, but RAF files describe where to unpack the contents.

Note: RAF also stands for Random Access File, Record Address File, and Resource Allocation Frame, but those terms have nothing to do with the file formats described on this page.

How to Open RAF File

Fujifilm images can be opened with Able RAWer, Fujifilm X Raw Studio, FastStone Image Viewer, Adobe Photoshop, XnView, and probably a number of other popular photo and graphics tools. The free RAF Viewer can also open and resize the file.

Mac you can open RAF files by default using Apple Photos without installing a third-party program.

RAF files used with Riot Games' League of Legends can be opened with Total Commander, as long as you also have the RAF Packer plugin installed. You may also have luck using RAFExtractor.

Tip: If you find that an application on your PC tries to open the file, but it's the wrong application or you want another installed program to open the file, learn how to change the default program for a specific file extension in Windows.

How to Convert RAF Files

The RAF Viewer program mentioned above can convert this format to JPG, GIF, TIFF, BMP, and PNG. You can also convert a file if you open it in Photoshop or Able RAWer and then use the program's menu options to save as a different format.

Adobe DNG Converter is a free file converter for Windows and macOS that can save RAF files (from some Fujifilm cameras) to DNG format.

Zamzar is another RAF file converter that can save files to a number of different image formats. Since Zamzar is a website, you don't need to download the converter to use it, so it works equally well on any operating system.

It is very likely that there is no need to convert the Riot archive file to any other archive format.

Still Can't Open the File?

Other file formats have file extensions that look very similar to RAF, but that doesn't mean they can be opened with the same program. It's likely that you're misreading the file extension, confusing unrelated formats if your file doesn't work with the suggestions above.

Some examples of similar file extensions include RAR, RAM (Real Audio Metadata), RAS (Remedy Archive System), and ARF.

Research that specific file extension for information on how to open/convert that format if you have one of those files or something completely different.

Final Thoughts

The most reliable way to handle a RAF file is to follow the process in order, verify each important setting, and test the result before moving on. Use the guidance above as a practical reference, then adjust the details for your device, software version, or specific goal.
