The easiest way would probably be downloading diff for Windows: http://gnuwin32.sourceforge.net/packages/diffutils.htm
You could also do something like:
最简单的方法可能是为 Windows 下载 diff：http: //gnuwin32.sourceforge.net/packages/diffutils.htm
您也可以执行以下操作：
dir directory1 > dir1
dir directory2 > dir2
comp dir1 dir2
Also, some versions of Windows comes with windiff, however that is a GUI tool
此外，某些版本的 Windows 带有windiff，但这是一个 GUI 工具

In Windows there is the fccommand. I think diffis way better, but if you want to use only what came with the installation, well, here you go! :)
在 Windows 中有fc命令。我认为diff这样更好，但如果您只想使用安装附带的内容，那么，就这样吧！:)

You can use windiff util included in Windows from NT version and up. Just run 'windiff' and a graphic tool will pop up.
您可以使用 Windows NT 及更高版本中包含的windiff util。只需运行“winddiff”，就会弹出一个图形工具。
File -> Compare directories
文件 -> 比较目录

This article describes how to use it from command line. Great benefit of this tool is that it is already included and you don't need to download and install anything.
本文介绍如何从命令行使用它。这个工具的一大好处是它已经包含在内，你不需要下载和安装任何东西。

To compare data with command prompt you can use
要将数据与命令提示符进行比较，您可以使用
COMP /a /l D:\Folder1\data.txt D:\Folder2\data.txt
COMP /a /l D:\Folder1\data.txt D:\Folder2\data.txt
There can be different options like specific numbers of lines to search and case insensitive search and even you can compare folders with command prompt. Here are other options to compare files and folders with command prompt.
可以有不同的选项，例如要搜索的特定行数和不区分大小写的搜索，甚至您可以将文件夹与命令提示符进行比较。以下是通过命令提示符比较文件和文件夹的其他选项。

Partial solution with ROBOCOPY
ROBOCOPY 的部分解决方案
A partial solution (and thus for me unfortunately a "non-solution", although I had high hopes for it initially), which may or may not be enough for you:
部分解决方案（因此对我来说不幸的是“非解决方案”，尽管我最初对它寄予厚望），这对您来说可能还不够：
It seems the ROBOCOPY tool can be (ab-)used to work as a kinda poor man's recursive comparison; with the unfortunate limitation, that it apparently doesn't compare file contents. It seems to compare sizes, datesand optionally attributes. The magic incantation for this would be:
似乎ROBOCOPY 工具可以（ab-）用作一个有点可怜的人的递归比较；不幸的是，它显然没有比较文件内容。它似乎比较大小、日期和可选的属性。对此的魔法咒语是：
ROBOCOPY path1 path2 /e /l /ns /njs /njh /ndl /fp /log:result.txt /it
where optionsmeaningseems to be:
/e- recurse, including empty directories;/l- only print a log, don't modify files;/ns /njs /njh- don't print file sizes, job summary, job header;/ndl- "don't log folder names"- NOTE: this reportedly will result in skipping cases of missing/superfluous empty dirs; if you don't use this, those should get logged, but you'll have to somehow remove non-differing dirs by other means;
/log:result.txt- write results to 'result.txt' file; I think this can be omitted and result will be shown on standard output then.
/e- 递归，包括空目录；/l-只打印日志，不修改文件；/ns /njs /njh- 不打印文件大小、作业摘要、作业标题；/ndl- “不记录文件夹名称”- 注意：据报道，这将导致跳过丢失/多余的空目录的情况；如果你不使用它，那些应该被记录，但你必须以某种方式通过其他方式删除非不同的目录；
/log:result.txt- 将结果写入“result.txt”文件；我认为这可以省略，然后结果将显示在标准输出上。
Additional options:
其他选项：
/it- I think this should be added if you want to compare attributes too - see an explanation on what "tweaked" files are.
/it- 我认为如果您也想比较属性，应该添加这个 - 请参阅有关“调整”文件是什么的解释。
Warning: does NOT compare file contents
警告：不比较文件内容
As I said above, this seems not to compare file contents, unfortunately. I verified this by running the following command first:
正如我上面所说，不幸的是，这似乎不是比较文件内容。我首先通过运行以下命令来验证这一点：
mkdir d1\a\b d2\a\b & echo x > d1\a\b\f & echo y > d2\a\b\f
Most of the time, this should produce files d1\a\b\f and d2\a\b\f with same timestamps, you can verify with dir d1\a\b\f d2\a\b\f. The robocopycall on d1 & d2 produced an empty result set for me.
大多数情况下，这应该生成具有相同时间戳的文件 d1\a\b\f 和 d2\a\b\f，您可以使用dir d1\a\b\f d2\a\b\f. robocopy对 d1 和 d2的调用为我生成了一个空结果集。
