What is an .BAY file?

.BAY is Casio RAW Image

A BAY file is a digital photograph captured by a Casio digital camera. It contains raw image data from the camera in a proprietary format that is unprocessed and uncompressed.

Camera Raw image files are not directly usable unless a program supports the file type and camera model used to capture the image. You can touch up BAY files with select image editors, such as PaintShop Pro and ACDSee, and then export them to standard raster formats such as .JPG or .BMP.

NOTE: Casio Camera RAW files also use the .RAW extension.
