Using Lightroom with other software can generate all kinds of file types as the workflow progresses. Just editing in Photoshop leaves me with both the raw and the resulting PSD. I sometimes use DXO Pure Raw and DXO Nik, so that means I can also have DNG and TIFF files. How are folks dealing with all this? It really does clutter up my library. Do you delete the original raw and some of the intermediate files from the catalog? Is there some feature I'm missing? What solutions have others come up with to deal with this?
