What to do if the git file is too large

As the file content becomes more and more complex, the size of the files maintained by the Git repository is also getting larger and larger. Problems can occur when the size of a file exceeds the limit set by Git. So, what should we do when the Git file is too large? This article will introduce several solutions.

Git’s file size limit

Git has a limit on file size. By default, Git's size limit for a single file is between 100MB ~ 1GB. This limit depends on the Git version and settings you are using.

If your file exceeds the limit set by Git, Git will not be able to accept the submission of the file. In this case, you need to find a way to shrink the file or handle the problem in other ways.

Method 1: Reduce the file size

First of all, you can solve the problem of too large Git files by reducing the file size. Specific methods include the following.

1. Compressed files

For text files (such as code files, configuration files, etc.), you can try to use a compression tool to compress the files to reduce the file size. Commonly used compression tools include gzip, tar, 7z, etc.

2. Split the file

If a file is too large, you can try to split it into multiple smaller files. Not only does this reduce the size of individual files, it also makes it easier to manage files.

3. Clean up historical versions

If your Git repository already has multiple historical versions of files, and these historical versions of files take up a lot of space, you can consider cleaning up some earlier versions. , only the latest version is retained.

Method 2: Using Git’s LFS

Git LFS (Large File Storage) is an extension provided by Git for processing large files. Using Git LFS you can place large binary files into a separate storage pool instead of storing them in a Git repository.

Using Git LFS has the following advantages:

• can save the size of the Git warehouse;
• can improve the performance of the Git warehouse, because Git LFS only retains Git Pointers to files in the warehouse without storing the actual file contents;
• Large files can be shared between multiple Git warehouses because the Git LFS storage pool can be used by multiple Git warehouses.

To use Git LFS, you need to install the LFS extension in your Git repository and configure the LFS storage pool address in the Git repository.

Method 3: Use SVN

If there are large files in your Git warehouse and you don’t want to use Git LFS, you can also consider converting the Git warehouse to an SVN warehouse. Unlike Git, SVN does not set explicit size limits for large files.

You can use the git-svn tool to convert a Git warehouse into an SVN warehouse. For specific methods, please refer to [git-svn official documentation](https://git-scm.com/docs/git-svn).

Conclusion

Through the introduction of this article, we can see that when encountering a situation where the Git file is too large, we can take a variety of measures to solve the problem. The specific approach depends on your actual needs. You can choose the method that best suits you according to the situation. No matter which method you choose, make sure you do it in a way that won't cause damage to your data, and back up your data just in case anything goes wrong.
