Batch file to compare 2 directories and get names of files that are different [dos]

Question

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?

EDIT I am currently creating 2 lists using dir and then doing a file compare. Now I just need to parse the output of the fc to only contain the file names.

fc /a "C:\whatever\text1.txt" "C:\whatever\text2.txt" >> "C:\whatever\differences.txt"

Solution 1

First do a dir /s on both folders. Then use fc /a to compare the results.

For anything better than that (depending in your needs) you'll need a specialized tool. For instance have a look at Windiff or WinMerge.

Solution 2

Batchfile

@echo off
if "%2" == "" GOTO Usage

cd /D %1
if errorlevel 1 goto usage

for %%x in (*.*) do if NOT exist %2\%%x echo missing %2\%%x
cd /D %2
for %%x in (*.*) do if NOT exist %1\%%x echo missing %1\%%x

goto end

:usage
echo Usage %0 dir1 dir2
echo where dir1 and dir2 are full paths
:end

Usage
