Hard Drives Syncing Question: Same Copies Under Different Folders in Drives

[75er]

I have several hard drives full of multiple copies of videos & photos some are in different folders in the drives

how can I sync the drives please?

I have
FreeFileSync paid/donation version 11.25
AllDup 4.5.22
Allway Sync 20.1 Pro

or you think there's a better suited app, would you please guide me to it

Are the directory trees in the same relative structures?

c:/videos/
c:/videos/1/
c:/videos/2/
c:/videos/3/

x:/backups/videos/
x:/backups/videos/1/
x:/backups/videos/2/
x:/backups/videos/3/

If so, FFS will easily handle that.

Unfortunately not
disk 1 has lot's of video clips and photos in a proper and better organized manner let's call it master disk
disk 2 has the same ones under different folders structure (minus the missing ones from the master disk )
I'd like to mirror the master disk, if I do it then folder structure is different in the disk 2 and I will end up multiple copies of the same ones under different folders in disk 1

want to Keep only 1 mirrored copy of disk 1 in the disk 2, nothing extra

Thank you everyone

I have started re-arranging the folders on disk 2 to roughly match disk 1.
(Couldn't do the two-way as the capacity wasn't enough in each)

Then tried eliminating large duplicate ones with AllDup
Then will start mirror syncing with FFS

all the best to you all
