Batch file to compare 2 directories and get names of files that are different [dos]
提问by Nick Sinas
I will have 2 directories, folder1 with a set files list, and folder2 with the same set file list but with more files. I need to get folder2's "other files"
Does something exist like file compare (fc) for directories to return the differences?
我将有 2 个目录，folder1 带有一个集合文件列表，folder2 带有相同的集合文件列表但是有更多的文件。我需要获取folder2的“其他文件”
是否存在类似文件比较（fc）的目录以返回差异？
EDITI am currently creating 2 lists using dirand then doing a file compare. Now I just need to parse the output of the fcto only contain the file names.
编辑我目前正在创建 2 个列表dir，然后进行文件比较。现在我只需要解析 的输出fc以仅包含文件名。
fc /a "C:\whatever\text1.txt" "C:\whatever\text2.txt" >> "C:\whatever\differences.txt"

First do a dir /son both folders. Then use fc /ato compare the results.
首先dir /s在两个文件夹上做一个。然后fc /a用来比较结果。
For anything better than that (depending in your needs) you'll need a specialized tool. For instance have a look at Windiffor WinMerge.
对于比这更好的任何东西（取决于您的需要），您将需要一个专门的工具。例如看看Windiff或WinMerge。
