I've got 2 very old Backups of a friends computer. They were simply copied into a folder each on an external Harddrive. Both are about 300GB in Size and the contents are very much alike but not identical and the folder-structure is different. I want to free that space and make one single Backup of those two. I think about 90% of the files are douplicates, but i dont want to miss the files that are not.
So what I need is a program that compares the files in two directories with all their subdirectories but ignoring these subdirectories. All files within Folder A should be compared with All Files in Folder B. All exact douplicates in Folder B should be marked/moved(/deleted). I will handle the remains in Folder B manually.
I've tried meld, I've tried Gnome-Commander (I'm using Xubuntu with XFCE)
I would enjoy a gui-solution but I should be able to handle terminal and scripts too. I thought it may be possible to build a file-list for both sides and pipe these to some diff-program, but how to do it exactly is out of my capabilities.
Well, looking forward to your answers, turtle purple
