Okay hope this makes some kind of sense, Once I've imported my photos in LR, then once I'm done in develop section, i then export them into a subfolder e.g. Landscape, BW etc..so my photos are categorised, but when i delete a picture in the library it will also delete the one in the subfolder, which i don't think is right ? otherwise I'm just ending up with countless doubles. Thanks in advance for any feedback.
