mark folder as binary in .gitattributes

Question

I have to include some folder to a repository but I don't want my git to modify it's content (line endings etc)

I already have some files that are marked as binary files in .gitattributes i.e. images:

*.png binary

but this rule specifies certain category of files - png files, however I want to achieve something like that:

/folder_which_i_want_to_mark_as_binary binary

The currently accepted answer did not work for me. Possibly the behavior changed in recent versions of git. Quoting from the manual of gitattributes:

The rules by which the pattern matches paths are the same as in .gitignore files (see gitignore[5]), with a few exceptions:

• negative patterns are forbidden
• patterns that match a directory do not recursively match paths inside that directory (so using the trailing-slash path/ syntax is pointless in an attributes file; use path/** instead)

Therefore, to treat a whole folder as binary, use the following syntax:

folder_which_i_want_to_mark_as_binary/** binary

Tested with git version 2.20.1.
