Compare two folders and output missing files in both folders
I would like to compare two folders, strictly for filenames. (Not the file contents). I am on windows 10 and would like to use command line tools.
Here is scenario that may explain the issue.
Folders
-------
source source2
- file_1 - file_1
- file_2 - file_2
- file_3 - file_4
- file_5 - file_5
- file_6 - file_7
Output should be:
-----------------
Source -> Missing files file_4
Source2 -> Missing files file_3
I did some research, and there are many diff tools, but I am not interested in comparing the file contents. All I want is compare two folders and output which files are missing in both folders (compared to the other one).
I prefer not to use Powershell.
Thank you.
robocopy (included in recent Windows versions) can do this in one pass:
given \source\ and \source2\ with some files which are common and files which exist only in either folder, running
robocopy source source2 /L /NJH /NJS /NP /NS
yields
D:\Users\me\test\source\
*EXTRA Datei only_in_source2.txt
Neue Datei only_in_source.txt
where lines starting with a * denote files only in source2 (independent of the OS language), and other lines denote files only in source.
The options suppress various output items, and /L takes care that differences are listed only, not copied.
This Powershell script does what you want.
$fso = Get-ChildItem -Recurse -path C:\Temp\Source
$fsoBU = Get-ChildItem -Recurse -path C:\Temp\Source2
Compare-Object -ReferenceObject $fso -DifferenceObject $fsoBU
That, and several other options, are discussed here: https://stackoverflow.com/questions/3804109/what-is-the-best-way-to-compare-2-folder-trees-on-windows
You can save the next code as ccomp.cmd, and then call it with the /? flag to find out how to use it (tested on Windows 7, Windows 10):

echo.
echo * Note 1:
echo - Files that are hidden and also have a Unicode path - are compared only by path, not also by size
echo - In some rare cases ^(for some Unicode file paths^) some files may be misreported
echo.
echo * Note 2:
echo - This program uses the ^"sort^" utility for sorting results, so the waiting time for the comparison of the two directories depends on (is a multiple of) n * log n ^(the time complexity for the quick sort algorithm ^(used in ^"sort^"^)^) - where - n is the total number of files in the two directories that are to be compared.
echo - The output of the program is Unicode
goto :eof
:PressAKey
set /p=%~1<nul
pause>nul
goto :eof
Do a dir /b /A-dof both folders to a file and compare these with findstr and the /VG: options
Given a sample tree:
> tree /f
X:.
│
└───Folders
├───source
│ file_1
│ file_2
│ file_3
│ file_5
│ file_6
│
└───source2
file_1
file_2
file_4
file_5
file_7
The following batch file:
:: Q:\Test\2019\02\19\SU_1407481.cmd
@echo off
Set "DirA=X:\Folders\source\"
Set "DirB=X:\Folders\source2\"
Dir /B /A-D "%DirA%*" >DirA.txt
Dir /B /A-D "%DirB%*" >DirB.txt
echo file(s) missing in %DirA%
findstr /VG:DirA.txt DirB.txt
echo fil(e) missing in %DirB%
findstr /VG:DirB.txt DirA.txt
yields this output:
> SU_1407481.cmd
file(s) missing in X:\Folders\source\
file_4
file_7
file(s) missing in X:\Folders\source2\
file_3
file_6
