Intro
If your a file is larger than 100MB, you will need to manage it with Git LFS.
I write the way down on this article about how to use Git LFS.
Since I have many opportunities to use Unity, I will write based this on a simple Unity sample.
Environments
| name | version |
|---|---|
| Unity | 2020.3.4f1 |
| Fork | 1.69.3.0 |
What is Git LFS?
Git is a distributed version control system, meaning the entire history of the repository is transferred to the client during the cloning process. For projects containing large files, particularly large files that are modified regularly, this initial clone can take a huge amount of time, as every version of every file has to be downloaded by the client. Git LFS (Large File Storage) is a Git extension developed by Atlassian, GitHub, and a few other open source contributors, that reduces the impact of large files in your repository by downloading the relevant versions of them lazily. Specifically, large files are downloaded during the checkout process rather than during cloning or fetching.

In a nutshell, it makes it easier and more convenient to work with large files on git.
And we can not manage a large file without Git LFS.

Experiment without Git LFS
We tested using Fork, a client tool for using git, to push a file larger than 100MB.
It failed as expected.
How to use
I use Git for Windows, which includes Git LFS, so I'll skip the installation steps.
First, copy the path to the large file.
Next, open the console and enter the following command.
$ git lfs track [path]
If successful, ".gitattributes" will be added and the lfs message will be written.
If you have already created commit that contains a large file, you have to enter the following command.
$ git rm --cached [path]
