我遇到了上述问题，为方便起见，我将使用一个小示例重新创建场景

您可以看到最后数据文件夹消失了。我想知道它是如何工作的，以及如何恢复丢失的文件夹。谢谢！
我的工作配置是“ git版本2.7.4； ubuntu 16.04LTS”。
以上是一个示例，在此我介绍项目中的实际操作。查找丢失的文件夹可能会有所帮助。
我想在本地创建一个分支以提高开发效率，因此我阅读了有关Git Branch和Git Stash的文档，但实际上很难做到这一点。 我一直在master分支上工作，还有一些尚未提交的更改，所以
git stash --keep-index -u
git stash apply
git stash -u
git checkout -b newbranch
git stash pop
git stash drop stash@{0}
在新分支上工作了几个小时之后，我突然意识到我丢失了几个以前在master分支上未跟踪并标记为.gitignore的文件夹。此外，我还发现一些未跟踪的文件夹没有丢失，它们也标记为.gitignore。
在git stash -u或git checkout -b之后，我没有注意到这些文件夹何时丢失？ 我切换回了Matser分支
git stash -u
git checkout master
，这些文件夹仍然丢失。
经过研究，我复制了上面的简单示例，并猜测这是造成损失的原因。
