Files with the .RAF extension contain digital photos saved exactly as they were captured by the digital camera sensor, in uncompressed form. RAF files can also contain an additional JPG version of the photo. The format is unique to high-end cameras made by Fuji, such as those from the Fine-Pix series.

To read RAF files, you need software that supports the format for the relevant camera model. For example, Photoshop only lets its users use some RAF files, captured by only some camera models.
