When using Git for file version control, sometimes you may encounter files that are too large. When the file is too large, it may cause problems such as slower Git execution speed, increased memory usage, or even failure of Git submission upload. This article will introduce several ways to deal with Git files that are too large.
1. Using Git LFS
Git Large File Storage (Git LFS for short) is an extension of Git, which is specially used to process large files. With Git LFS, Git no longer stores files in a repository, but instead links them to a specific repository. This method can avoid an excessively large version library caused by too many large files, thereby improving Git operation performance.
Next, we will introduce how to use Git LFS:
brew install git-lfs
git lfs install
git lfs track "*.png"
git lfs push origin master
2. Use Git Annex
Git Annex is another extension of Git and is also used to manage large files. But unlike Git LFS, Git Annex will not replace the original Git file management, but will serve as a supplement to Git file management. Large files managed by Git Annex are not downloaded to the local Git repository. Instead, they are stored on the local disk and a pointer to the large file is stored in the Git repository.
The following describes how to use Git Annex:
brew install git-annex
git annex init
git annex add large_file.mp4
git commit -m "add large_file.mp4"
git annex get large_file.mp4
3. Use Git repack compressed version Library
In addition to using Git LFS, Git Annex and other tools to manage large files, we can also try to use Git's own repack tool to compress the repository to reduce the size of the repository. The following describes how to use the repack tool:
git repack
git repack -a -d
git gc
4. Use Git BFG
Git BFG is Git Abbreviation for backup filter, it is a simple and practical Git tool. It is based on the official Git tool and can help Git users better manage Git version control libraries. Using Git BFG can help you delete some useless files and history records in the Git version control repository more easily. The following is an introduction to how to use Git BFG.
brew install bfg
bfg
command to delete unnecessary files. Pay attention to replace file-to-remove
with the name of the file that needs to be deleted. Wildcards are also supported: bfg --delete-files file-to-remove
git reflog expire --expire=now --all && git gc - -prune=now --aggressive
git push origin --force
Summary :
For the problem of Git files that are too large, we can use various processing methods such as Git LFS, Git Annex, Git repack and Git BFG. These tools will all help us, we just need to choose according to the actual situation and needs. If you often face the problem of Git files that are too large, we recommend that you try the methods described above.
