Compare multiple subfolders (child) with a single parent

[CorK]

After importing the photos of my camera to my laptop, I moved some photos to their own folder (albums). Now, I'd like to compare the source (camera) and backup (laptop). If a source/camera photo is in any of the subfolders of my laptop it shouldn't be imported again.

ATM, I import all new photos from my camera to the main folder of my laptop. I then compare the main folder with its subfolders, one by one, and remove duplicates from the main folder.

How can this be done more efficiently?

Note: filtering by date only isn't sufficient.

Here's a visualistation of my folder structure:
Camera/
-A
-B
-C
-D
-E

Laptop/
- A
- B
- personal/
- C
- D
- work/
- E

Unfortunately, FFS can only make left and right locations be identical in structures. You would have to have multiple pairs and change the inclusion filter to only look at the subfolders you want. So the first would be "Camera\" and "Laptop\", but you would change the include filter from "*" to "A\" and "B\"

a different program can do this. beyond compare by scootersoftware. it allows you to collapse the directory structure and do a flat comparison of contents of subfolders. you can also script jobs. i like ffs better for straight syncing but bc is much more flexible (and complex, etc...) for edge cases like this.
