right Ive got about near enough a 500+ folders all filled with my pictures on a 120gb hdd now these files and folders are a mix of all my backups of images combined (because I forgot which one was hwere and I noticed i missed a few on my last backup) so i thought Id create a new directory so I know everything is their. but to import it to lightroom and filter out all the duplicates you have to go through folder to folder and 500+ would take ages so any software suggestions ?
