当我 git checkout< revision> ，那么这会将整个项目返回到它的状态，还是只重新创建那个特定修订版中更改的文件？
例如：如果我的文件夹除了.git repo和I git checkout master 之外完全是空的，那么生成的文件将是其中的项目整体，还是只有在最近的提交中更改过的文件？
我问，因为我在各个点（从头开始）检查我的项目，该项目的规模正在缓慢增长，正如人们所预料的那样，每个结账的规模都有很大的不同。

您是否考虑到未跟踪的文件？你提交了，然后删除大文件？根据您在问题中提供的信息，我们可以做的不过是推测尺寸差异很大的原因。
Newb question, I want to make sure I understand this.
When I git checkout <revision>, does this return the entire project to its state at that moment, or does it only recreate the files changed in that particular revision?
For example: If my folder was completely empty besides the .git repo, and I git checkout master, will the resulting files be the project in its entirety, or only the files changed in the most recent commit?
I ask, because I am checking out my project at various points (starting from the beginning), and instead of the project slowly growing in size as one would expect, the size of each checkout is varying quite a lot.

If your working tree and staging area are completely empty (besides the .git subdirectory, of course) and you run
git checkout <revision>then your working tree and staging area will perfectly reflect the contents of that particular revision.
On the other hand, if your working tree is not empty when you run git checkout, what happens is much more subtle, and may be broken down into three cases:
[...] the size of each checkout is varying quite a lot.
Are you taking into account untracked files? Did you commit, then later remove large files? On the basis of the information given in your question alone, we can do little more than hypothesize about the reason why the size varies a lot.
