I have 5 old hard drives that have been replaced over time with newer, larger hard drives. I kept the old ones as backups. Now I want to copy all the contents of the old drives onto one, very large hard drive. Is there a good utility program that can search through and identify the duplicates and then allow me to delete all duplicates and just keep one copy of each file?
How can I best merge data from multiple hard drives and find duplicate files?
