Happy you. I have Nikon D70 that produces NEF (.nef) and then I run
a script to create corresponding jpegs (.nef.jpg to tell me that
there's a high-quality NEF available). So if it only would be
possible to to have an option to make KPA ignore all .nef files
(but not .nef.jpg) I'd be happy..
File exclusion / filter has been discussed earlier and no actual
decisions have been made. I'm really looking forward to see Tuomas
finish the SQL backend: performance and possibility to manage file
types.. But if there will be some modification on file name / type
recognition I think this needs to be discussed again to find the
Performance and scalability are absolutely essential for this kind of
application. If it doesn't work well in all respects on very large
collections of images, it isn't worthwhile to have to learn the added
complexity. That includes things like selecting the right images.
