The company I work for has a database of around 1,000,000 JPG images. We take RGB images, convert them to CMYK, process and print them. The original files to be kept in the database are supposed to remain RGB. We believe that there was a problem with our archival process which may have filtered a significant number of CMYK formatted images back into our archive.

We need to find the CMYK images and delete them but leave all RGB images intact. Obviously with a million files, this would be a daunting task to open each one to determine its format.

Does anyone know of a software tool that can determine whether images are RGB or CMYK either without opening them or by batch processing and listing results?

Thanks in advance
Chad
