Finding Duplicate Files

[Jonathan Roberts]

Hey all,

I've got into a bit of a muddle with my backups...more than a little in fact!

I have several folders each approx 10-20 Gb in size. Each has some
unique material and some duplicate material, and it's even possible
there's duplicate material in sub-folders too. How can I consolidate
all of this into a single folder so that I can easily move the backup
onto different mediums, and get back some disk space!?

Thanks in advance,

Jon
