I am using Fast Raw Viewer for culling images as it's much quicker than LR. For images already cataloged in LR how can you cull those images with Fast Raw Viewer and avoid the dreaded ? symbol saying the pics are now missing?
The ? is not a problem. Just click one and locate it in the _Rejected sub-folder. LrC will find all the files FRV moved there. You can then use LrC to delete them if you wish.
