When opening in the File Browser a directory which contains tiff or dng files of large size, those files are not listed among the thumbnails. Files of those types having smaller size are displayed fine.
The file sizes in question are about 2.5Gb and the resolution is around 23000x18000 pixels. These are scans of large format negatives.
Is there an explicit limit on the supported file size in RawTherapee and if there is, are there specific issues associated with lifting that limit (apart from the linear performance hit)?
