Using git subtree to export a directory (with its history) from one git repository to another:

1. git subtree add --prefix=local_directory https://github.com/account_name/other_project_to_commits master
2. git subtree pull --prefix=local_directory https://github.com/account_name/other_project_to_commits develop
3. git subtree push --prefix=local_directory https://github.com/account_name/other_project_to_commits develop

If you prefer to avoid repeating the repository URL, then you can add it as a remote:

1. git remote add -f -t master --no-tags remote_name https://github.com/account_name/other_project_to_commits.git

Examples of remote name and local .git directory:

1. git subtree add --squash --prefix=local_directory file:///D:/other_project_to_commits/.git master

How to extract a single file with its history from a git repository

These steps show two less common interactions with git to extract a single file which is inside a subfolder from a git repository. These steps essentially reduce the repository to just the desired files and should performed on a copy of the original repository (1.).

First the repository is reduced to just the subfolder containing the files in question using git filter-branch --subdirectory-filter (2.) which is a useful step by itself if just a subfolder needs to be extracted. This step moves the desired files to the top level of the repository.

Finally all remaining files are listed using git ls, the files to keep are removed from that using grep -v and the resulting list is passed to git rm which is invoked by git filter-branch --index-filter (3.). A bit convoluted but it does the trick.

1. copy the repository to extract the file from and go to the desired branch
