How to Upload a Lot of Files to Github
Even though GitHub tries to provide plenty storage for Git repositories, information technology imposes limits on file and repository sizes to ensure that repositories are easy to work with and maintain, equally well equally to ensure that the platform keeps running smoothly.
Individual files added via the browser IDE are restricted to a file size of 25 MB, while those added via the command line are restricted to 100 MB. Beyond that, GitHub volition beginning to cake pushes. Individual repositories, on the other manus, are capped to a maximum of 5 GB.
While it's likely that about teams won't run upwards against these limits, those who exercise accept to scramble for a solution. For example, if you're only uploading lawmaking, y'all won't demand to worry virtually this. However, if your project involves some kind of data, such as data science projects or machine learning analysis, then well-nigh probable you will.I
n this commodity, we'll go over situations that can contribute to large repositories and consider possible workarounds—such as Git Large File Storage (LFS).
The Root of Big Repositories
Let's cover a few mutual activities that can outcome in especially large Git files or repositories.
Backing Upwardly Database Dumps
Database dumps are usually formatted equally big SQL files containing a major output of data that can be used to either replicate or support a database. Developers upload database dumps alongside their project code to Git and GitHub for 2 reasons:
- To keep the land of data and lawmaking in sync
- To enable other developers who clone the project to hands replicate the data for that point in fourth dimension
This is non recommended, as information technology could cause a lot of problems. GitHub advises using storage tools like Dropbox instead.
External Dependencies
Developers ordinarily use package managers like Bundler, Node Package Manager (npm), or Maven to manage external project dependencies or packages.
But mistakes happen every day, so a programmer could forget togitignore such modules and accidentally commit them to Git history, which would bloat the total size of the repository.
Other Large Files
Aside from database dumps and external dependencies, there are other types of files that tin can contribute to bloating up a repository file size:
- Big media assets: Avoid storing large media avails in Git. Consider using Git LFS (run across below for more details) or Git Annex, which allow you to version your media assets in Git while actually storing them outside your repository.
- File archives or compressed files: Unlike versions of such files don't delta well confronting each other, and so Git can't store them efficiently. It would exist better to store the individual files in your repository or store the archive elsewhere.
- Generated files (such as compiler output or JAR files): Information technology would exist meliorate to regenerate them when necessary, or store them in a package registry or even a file server.
- Log and binary files: Distributing compiled lawmaking and prepackaged releases of log or binary files within your repository can bloat it upward speedily.
Working with Large Repositories
Imagine you run the controlgit push and afterwards waiting a long time, you become the error messagefault: GH001 Large files detected. This happens when a file or files in your Git repository accept exceeded the immune capacity.
The previous section discussed situations that could lead to swollen Git files. Now, let's look at possible solutions.
Solution one: Remove Large Files from Repository History
If y'all discover that a file is too large, one of the short-term solutions would exist to remove it from your repository. git-sizer is a tool that can aid with this. It's a repository analyzer that computes size-related statistics about a repository. Merely simply deleting the file is non enough. Yous have to besides remove information technology from the repository's history.
A repository'south history is a record of the state of the files and folders in the repository at dissimilar times when a commit was made.
As long every bit a file has been committed to Git/GitHub, simply deleting it and making another commit won't work. This is because when y'all push button something to Git/GitHub, they keep rails of every commit to allow you to roll dorsum to any place in your history. For this reason, if you brand a serial of commits that adds and then deletes a large file, Git/GitHub will yet store the large file, so you can coil back to it.
What y'all need to do is ameliorate the history to get in seem to Git/GitHub that y'all never added the large file in the first identify.
If the file was simply added in your last commit earlier the attempted button, yous're in luck. You can simply remove the file with the following command:
git rm --cached csv_building_damage_assessment.csv (removes file)
git commit --ameliorate -C HEAD (amends history)
Simply if the file was added in an earlier commit, the process will exist a bit longer. You tin either use the BFG Repo-Cleaner or you can run git rebase or git filter-co-operative to remove the file.
Solution two: Creating Releases to Packet Software
As mentioned before, one of the ways that repos tin get bloated is by distributing compiled code and prepackaged releases within your repository.
Some projects crave distributing large files, such every bit binaries or installers, in add-on to distributing source code. If this is the example, instead of committing them as office of the source lawmaking, you can create releases on GitHub. Releases allow you lot to parcel software release notes and links to binary files for other people to apply. Be aware that each file included in a release must be under two GB.

Solution 3: Version Big Files With Git LFS
The previous solutions accept focused on how to avoid committing a big file or on removing information technology from your repository. What if you desire to go on it? Say you're trying to commitpsd.csv, and you get thetoo large file error. That's where Git LFS comes to the rescue.
Git LFS lets you push files that are larger than the storage limit to GitHub. It does this by storing references to the file in the repository, but not the actual file. In other words, Git LFS creates a pointer file that acts as a reference to the actual file, which volition be stored somewhere else. This pointer file volition be managed past GitHub and whenever you clone the repository down, GitHub will use the pointer file every bit a map to go and find the large file for you.
Git LFS makes utilise of a method chosenlazy pull and fetch for downloading the files and their dissimilar versions. By default, these files and their history are non downloaded every time someone clones the repository—simply the version relevant to the commit being checked out is downloaded. This makes it like shooting fish in a barrel to proceed your repository at a manageable size and improves pull and fetch time.
Git LFS is ideal for managing large files such every bit audio samples, videos, datasets, and graphics.
To get started with Git LFS, download the version that matches your device's OS here.
- Set up Git LFS for your account past running
git lfs install - Select the file types that yous want Git LFS to manage using the command
git lfs runway "*.file extension or filename". This will create a .gitattributesfile. - Add together the
.gitattributesfile staging area using the commandgit add .gitattributes. - Commit and push button only as you normally would.
Please notation that the in a higher place method will work only for the files that were not previously tracked past Git. If you already take a repository with large files tracked by Git, you need to migrate your files from Git tracking togit-lfs tracking. Simply run the following command:
git lfs migrate import --include="<files to be tracked>"
With Git LFS now enabled, you'll be able to fetch, modify, and push large files. Nonetheless, If collaborators on your repository don't accept Git LFS installed and prepare, they won't accept access to those files. Whenever they clone your repository, they'll but be able to fetch the pointer files.
To become things working properly, they need to download Git LFS and clone the repo, just like they would any other repo. Then to get the latest files on Git LFS from GitHub, run:
git lfs fetch origin primary
Conclusion
GitHub does not piece of work well with large files but with Git LFS, that can be circumvented. However, earlier you lot make any of these sensitive changes, like removing files from Git/GitHub history, it would be wise to back upward that GitHub repository first. One wrong command and files could exist permanently lost in an instant.
When you back up your repositories with a tool like BackHub (now function of Rewind), yous can easily restore your backups straight to your GitHub or clone directly to your local machine if annihilation should go incorrect.
