I've currently got around 2TB of CR2 Canon RAW files, 1TB of MOV/MP4, 600GB of JPGs, - I'm pretty sure a lot of that is duplicate files, but not in any sort of organised back up sense! The storage is there to do that but I want to get everything in the one place then get a proper backup in place. (4TB, 2TB, 5x1TB) Adobe Lightroom has an option to just re-import files from all over the computer and you can tell it to "Ignore Duplicates" however I'm not sure how robust that is... (It also seems to have loads of issues with video files importing so a lot don't get imported!) Does anyone have any suggestions on programs that could help solve this issue? I'd just hate to have a program think something is a duplicate to then end up deleting something there is only one of. (Yes, I know, if it's so important I should have had it better organised and backed up haha) Any help is much appreciated!!!
