Renaming file name on LR4 on Mac OS 10.6
Hello,
I want to replace the 8 first digits of my file name by 3 new digits (Ex: my actual name is : "100527CA_R05375.jpg" to be modified into "CAM_R05375.jpg").
I want to this in LightRoom in order to not lose the modification historic. The LR build-in renaming does not do that. Is there any plug-in or some other way.
Thank you for your help.
