Then get error message:

Does anyone know how to compress folder with brotli?

brotli can only compress a file or a single stream of data. Just like gzip, xz, lzip, etc. To compress a directory, you would do what all archivers do, which is to convert the information in the directory into a single stream of data and write that to a file.

You did not provide a clue to your operating system in the question or tags, but on Unix-like systems, tar is used to take a directory and all of its contents in files, subdirectories, symbolic links, etc., and convert those to a single stream of data. Then you can use bro on that, as you would use any other compressor gzip, xz, etc. on it.
