Photo mechanic is great, you can import from a card and put the files on any mounted drive. You can set the import from a card to rename the files by date or other Exif info and into directories in the same way. It can browse directories without importing. I don't think it can find duplicates, I typically I use a file duplicates tool for that type of thing. Adobe's Bridge product also does some of this, but I haven't used that in a few years.
