is there a git command that will list only the folders that are different between 2 branches. I have to create a Powershell script to detect what root folders have changed to determine what VSTS Build to run. So I will re-phrase the question:

I need to be able to run a programmatic command like 

git diff branchA..branchB | some-parser-that-outputs-a-list-of-root-folders

the result should look like with 

.\codebase1
.\codebase3
.\codebase5

Git doesn't have a pushbutton for this. I don't know powershell, so I'll give a bash answer. To list trees piecemeal (non-recursively), git ls-tree. To pick only folders, from ls-tree output, grep ^04. To diff those, diff them. On Linux it'd be something like

diff -u0 \
        <(git ls-tree branchA | grep ^04) \
        <(git ls-tree branchB | grep ^04)

suitably munged to strip details you don't want, but as I recall Windows has trouble with process substitution so you'll need to run it through temp files unless powershell has a better way.
