Files panel

This area of the main window contains all images in the selected folder of the virtual folder tree.

JpegMedic file panel

Every image in the list is accompanied with a description that contains system data about this JPEG image: file name (if the image was opened via the file system scan), camera name, date, offset, integrity percentage (for broken images).

Each line of the Files panel represents an individual JPEG file, where the first image in the line is the main image and all other images in the same line are thumbnails extracted from EXIF or JFIF data.

A checkbox next to an image allows you to select this image for export.
