I am running on Windows 10, NTFS, long paths enabled in the registry.

NTFS as well as almost all other FS does not allow to a path entry have length more then ~255. While the entire path may have up to ~32k characters length.

You need to limit {filename}.
By default it has no length limitation:

gallery-dl/gallery_dl/extractor/kemonoparty.py

Line 26 in f1cab23

filename_fmt = "{id}_{title}_{num:>02}_{filename}.{extension}"

Use (in your config file), for example: {filename[0:180]} instead of {filename}.

So, the full line (with the default filename pattern) will look like:

"filename": "{id}_{title}_{num:>02}_{filename[0:180]}.{extension}"

Can it be set globally?

[LurkerHub]

Use (in your config file), for example: {filename[0:180]}.

Thank you, it worked!

@alexolog You mean a global limit on filename length? No, that's not possible at the moment. (#814)

[alexolog]

I actually meant configuring a filename format to apply globally, which would also (indirectly) fix the length problem

[mikf]

That's possible by setting filename directly inside the extractor block, but it is basically impossible to have a filename format string that works for all sites, except maybe {filename}.{extension} or {filename[:250]}.{extension}

{
    "extractor": {
        "filename": "`{filename}.{extension}`"
    }
}
