Conditions for large files→
GitHub Enterprise limits the size of files allowed in repositories, and will block a push to a repository if the files are larger than the maximum file limit.
Removing files from a repository's history→
To remove a large file from your repository, you must completely remove it from your local repository and from your GitHub Enterprise Server instance.
Distributing large binaries→
Some projects require distributing large files, such as binaries or installers, in addition to distributing source code.
