Some digital cameras can simultaneously capture both JPEG + RAW files. This will result in two separate files for each photo you take: one JPEG file and one RAW file.
This program will find and delete the unnecessary JPEG files to save disk space. The corresponding RAW files are NOT affected.

Program does not include a setup routine. Just double-click on JPEGcleaner.app to run.
Mac only (for now).
