git large pack file, delete and rewrite?
提问by agrT
I have a relatively small git repository containing a standard Wordpress installation. However, I accidentally added a "concept" folder in the repository which contains many large psdfiles.
我有一个相对较小的 git 存储库，其中包含标准的 Wordpress 安装。但是，我不小心在包含许多大psd文件的存储库中添加了一个“概念”文件夹。
The problem is that now, after 50 commits, git has created a "pack" file, which is 1,3 GB.
问题是现在，在 50 次提交之后，git 创建了一个 1.3 GB 的“pack”文件。
To downsize the pack folder I tried to remove my "concept" folder via:
为了缩小包文件夹的大小，我尝试通过以下方式删除我的“概念”文件夹：
git filter-branch --index-filter 'git rm -rf --cached --ignore-unmatch DIRECTORY/' --prune-empty --tag-name-filter cat -- --all
and afterwards
然后
git gc --aggressive --prune
After the execution of these commands, my "concept" folder was deleted from the file system and from all commits but the pack file is still exactly 1,3 GB
执行这些命令后，我的“概念”文件夹从文件系统和所有提交中删除，但包文件仍然正好是 1,3 GB
Is there anything else I can do to reduce the size of the pack folder?
我还能做些什么来减小包文件夹的大小？

I mentioned before that a git gcalone can actually increase the size of the repo).
我之前提到过，一个git gc人实际上可以增加 repo 的大小）。
The commands I was listing were:
我列出的命令是：
# remove the temporary history git-filter-branch otherwise leaves behind for a long time
rm -rf .git/refs/original/ && git reflog expire --all && git gc --aggressive --prune=now
If that doesn't work, check out the BFG tool.
如果这不起作用，请查看BFG 工具。
You will find an even more complete gc in "How to remove unreferenced blobs from my git repo"
你会发现在“一个更完整的GC如何从我的混帐回购协议中删除未引用的斑点”
This articlesuggests a similar approach:
这篇文章提出了一种类似的方法：
rm -rf .git/refs/original/
git reflog expire --expire=now --all
git fsck --full --unreachable
git repack -A -d
git gc --aggressive --prune=now
