If you re comparing different branches  you need to use -- to separate a Git revision from a filesystem path  For example  with two local branches  master and bryan-working     git diff master -- AFolderOfCode  bryan-working -- AFolderOfCode    Or from a local branch to a remote     git diff master -- AFolderOfCode  origin master -- AFolderOfCode

Add Beyond Compare as your difftool in Git and add an alias for diffdir as   git config --global alias diffdir    difftool --dir-diff --tool bc3 --no-prompt    Get the gitdiff as   git diffdir 4bc7ba80edf6  7f566710c7   Reference  Compare entire directories w git difftool   Beyond Compare

To use Beyond Compare as the difftool for directory diff  remember enable follow symbolic links like so   In a Folder Compare View  rarr  Rules  Referee Icon      And then  enable follow symbolic links and update session defaults       OR   set up the alias like so   git config --global alias diffdir  difftool --dir-diff --tool bc3 --no-prompt --no-symlinks    Note that in either case  any edits made to the side  left or right  that refers to the current working tree are preserved

You should make a habit of looking at the documentation for stuff like this  It s very useful and will improve your skills very quickly  Here s the relevant bit when you do git help diff     git diff  options   --no-index   --   lt path gt   lt path gt    The two  lt path gt s are what you need to change to the directories in question

What I was looking for was this  git diff  lt ref1 gt    lt ref2 gt   lt dirname gt

If you want to exclude the sub-directories  you can use  git diff  lt ref1 gt    lt ref2 gt  --   git diff  lt ref1 gt    lt ref2 gt  --name-only   grep -v

Not only you can add a path  but you can add git diff --relative to get result relative to that folder  git -C a folder diff --relative  And with Git 2 28  Q3 2020   the commands in the  quot diff quot  family learned to honor the  quot diff relative quot  configuration variable  See commit c28ded8  22 May 2020  by Laurent Arnoud  spk    Merged by Junio C Hamano -- gitster -- in commit e34df9a  02 Jun 2020   diff  add config option relative Signed-off-by  Laurent Arnoud Acked-by    o  n Tr n C  ng Danh The diff relative boolean option set to true shows only changes in the current directory value specified by the path argument of the relative option and shows pathnames relative to the aforementioned directory  Teach --no-relative to override earlier --relative Add for git-format-patch 1  options documentation --relative and --no-relative  The documentation now includes   diff relative  If set to  true    git diff  does not show changes outside of the directory and show pathnames relative to the current directory
