When processing the data found that there are a few types of duplicates.
A small amount of images in "original" also exist in "recent"
For example:
danbooru2023/recent/1400/6973400.jpg
danbooru2023/original/0400/6973400.jpg
(Think there is a small overlap in the range of ids "original" and "recent" cover)

Also some images appear twice with different extensions. For example:
danbooru2023/original/0400/3800400.png
danbooru2023/original/0400/3800400.jpg
(This also happens across parts. For example, the jpg will be in "original" and the png in "recent" or vice versa)

Im only processing files that end with png/jpg/jpeg so there might be other similar issues with other file types.
On the data I have downloaded, found 36970 dupes.

I've attached the code I used while figuring this out, in case its helpful (quality isn't great but should work)

def get_files_in_folder(folder_path):
    file_list = []
    for root, dirs, files in os.walk(folder_path):
        for file in files:
            full_path = os.path.join(root, file)
            file_list.append(full_path)
    return file_list

for itemPath in filePaths:
    imageId=int(os.path.basename(itemPath).split(".")[0])
    if(imageId in filePaths3):
        otherPath=filePaths3[imageId]
        if(itemPath.endswith(".png") and (not otherPath.endswith(".png"))):
            print("------------")
            print(itemPath)
            print(otherPath)
            print("would remove: "+otherPath)
