Brotli .br archive format created by brotli.exe not supported? - Win8.1

[jack4455667788]

Using the latest x64 bit version available (https://github.com/mcmilk/7-Zip-zstd/releases/download/v22.01-v1.5.5-R3/7z22.01-zstd-x64.exe) there is no brotli ".br" archive format support (which is the default output of the google brotli executable - https://github.com/google/brotli).

Attempting to open an existing .br file fails with "Cannot open file XXX as archive"

Can this be fixed? Or can I convert the .br somehow to be usable in 7zip?

Has this .br file some magic in the beginning? If not, then I can not support this.

Unless the magic is a single hex "A" (followed by varying 1 or 2 hex digits perhaps signifying something) - no, from my testing it doesn't appear that it does.

just use the file extension .br, then try brotli, it would be great helpful
