Archivos duplicados

Hi Greg.Thank you for your help. I'm importing the items from the camera with Bridge. When the files are in my computer (in my second internal HDD) I open Organizer and pictures and video get imported into the catalog, but duplicated. I have always done this way without any issue till some months ago. 

How exactly are you importing the photos and videos?  Where are the original files stored?  If you are somehow using Bridge, your workflow is creating duplicate files and it is the OS, presumably Windows that is copying the files to the same folder and is adding the -1 suffix.  Without more information, this sounds like a user error and has nothing to do with the program.  If the original files are stored on your hard drive, you should be importing them into the Organizer via Import>From Files and Folders.
