Thanks All. I've cloned git-filter-repo and I shall shortly give it a try. First step is to get Python 3 installed (I'm on Windows).

Let's say the original repo had a file structure like the following: module/ foo.c bar.c otherDir/ blah.config stuff.txt zebra.jpg If the request is to e.g. take module/ and all files within it with their history and make a new repository out of it, with module/ being remapped to the root of the repository, then you would want: git filtrer-repo --subdirectory-filter module and yes, this looks exactly like filter-branch; that's the one flag I copied from it. So this one usecase maps directly between the two tools. In contrast, if you wanted to keep all files from the original repo but move everything into a subdirectory named "myProject" (so that e.g. module/foo.c became myProject/module/foo.c), possibly in preparation for merging your repo into some larger monorepo, then you'd want to pass `--to-subdirectory-filter myProject` as in the link you pointed out. filter-branch doesn't have an equivalent. Hope that helps, Elijah
