Since you are searching for this issue, you must have realised that git does not support storing empty folders/directories.
Currently the design of the Git index (staging area) only permits files to be listed, and nobody competent enough to make the change to allow empty directories has cared enough about this situation to remedy it.
Directories are added automatically when adding files inside them. That is, directories never have to be added to the repository, and are not tracked on their own.

All the content is stored as tree and blob objects, with trees corresponding to UNIX directory entries and blobs corresponding more or less to inodes or file contents. A single tree object contains one or more tree entries, each of which contains a SHA-1 pointer to a blob or subtree with its associated mode, type, and filename.

Below we propose two solutions, depending on how you want to use those empty folders.
Solution A – The folders will always be empty
There are scenarios where the empty folders should always remain empty on git no matter what the local copy has inside them.
Such a scenario would be, wanting to add on git folders where you will build your objects and/or put temporary/cached data.
In such scenarios it is important to have the structure available but never to add those files in git.
To achieve that, we add a .gitignore file in every empty folder containing the following:
# git does not allow empty directories. # Yet, we need to add this empty directory on git. # To achieve that, we created this .gitignore file, so that the directory will not be empty thus enabling us to commit it. # Since we want all generated files/folders in this directory to be ignored by git, we add a rule for this. * # And then add an exception for this specifc file (so that we can commit it). !.gitignore

The above .gitignore file, instructs git to add this file on the repository, and thus add the folder itself while ignoring ALL other files.
You can always update your .gitignore file to allow additional files to be added on the repository at any time.
This way you will never get prompted for temporary files that they were modified/created as part of the status of your repository.
Automation
A way to achieve this automatically, and place a copy of the .gitignore file in every empty folder would be to use the following command to copy an existing .gitignore file in all empty folders.
find $PATH_TO_REPOSITORY -type d ! -path "*.git*" -empty -exec cp .gitignore '{}'/ \;
The above command assumes that there is a .gitignore file in the folder that we are executing from, which it will copy in every empty directory inside the folder that the variable $PATH_TO_REPOSITORY is pointing to.

Solution B – Files will be added eventually to the folders
There are scenarios where the empty folders will be filled at a later stage and we want allow those files on git.
Such a scenario would be, wanting to add on git folders where right now are empty but in some time we will add new source code or resources there.
To achieve that, we add an empty .gitkeep file in every empty folder.
The above .gitkeep file is nothing more than a placeholder.
It is not documented, because it’s not a feature of Git.
It’s a dummy file, so git will not process the empty directory, since git tracks only files.
Once you add other files to the folder, you can safely delete it.
This way you will always get prompted for files that they were modified/created as part of the status of your repository.
Automation
A way to achieve this automatically, and place a copy of the .gitkeep file in every empty folder would be to use the following command to create an empty .gitkeep file in all empty folders.
find $PATH_TO_REPOSITORY -type d ! -path "*.git*" -empty -exec touch '{}'/.gitkeep \;
The above command will create in every empty directory inside the folder that the variable $PATH_TO_REPOSITORY is pointing to a new .gitkeep file.
Finally, push the changes to the git repository
After you create/copy the files, navigate to the repository, add all the new files to the commit, commit them and push them to the repository.
cd $PATH_TO_REPOSITORY; # Create a new branch git checkout -b empty_folders; # Add all modified files to the next commit. git add .; git commit -m "Minor change: Adding all empty folders to the repository."; git push -u origin empty_folders;
