Microsoft tool to compare 2 directories

[falcios]

Is there a Microsoft tool that will compare 2 directories?

I'm looking to see if there are duplicate files and their locations. Single files on one drive only, etc.

Thanks in advance.

Yes "windiff.exe", but i'm not sure where to download it from, i have to search (but actually i don't have time).

Thanks for the response. I already have windiff and it does compare directories if there are the same. I was looking for a utility to go through folders and subfolders and output list of the what one folder has or has not, if there are duplicates or a single file.

Thanks.

I was looking for a utility to go through folders and subfolders and output list of the what one folder has or has not, if there are duplicates or a single file.

Windiff should be capable of that:
Use the menuitems listed under "Options" (and "Expand") in the menubar to list the information you need ("Show Identical Files", "Show Left-Only Files", ...).

Something like this, perhaps?

Code: Select all

@echo off
setlocal EnableDelayedExpansion

if "%~2" neq "" goto begin
echo CompDirs.bat dir1 dir2
echo/
echo Compare files in both directories
goto :EOF

:begin

rem Populate first tree
pushd "%~1" 2>NUL || (echo First directory not found & goto :EOF)
for /R %%a in (*.*) do (
   set "name=%%~a"
   set "file1["!name:*%cd%\=!"]=1"
)

rem Populate second tree and report files in both trees
popd
cd "%~2" 2>NUL || (echo Second directory not found & goto :EOF)
echo Files in both directories:
echo/
for /R %%a in (*.*) do (
   set "name=%%~a"
   set "name=!name:*%cd%\=!"
   if defined file1["!name!"] (
      echo !name!
      set "file1["!name!"]="
   ) else (
      set "file2["!name!"]=1"
   )
)
echo/
echo/

echo Files in first directory only:
echo/
for /F "tokens=2 delims=[]" %%a in ('set file1[ 2^>NUL') do echo %%~a
echo/
echo/

echo Files in second directory only:
echo/
for /F "tokens=2 delims=[]" %%a in ('set file2[ 2^>NUL') do echo %%~a

Note that this is just a proof of concept, so several features may be added.

Thanks Antonio for the script.

Can you tell me where do I specify the folders to compare? Can it prompt me to enter the folder names?

Thanks.

By default you would pass the two folders to the script as parameters, using quotation marks if you've got spaces in your folder names for some reason.

Code: Select all

compdirs.bat "C:\Users\John\Desktop\Some Folder\" "D:\backup\Some Other Folder\subfolder1\"

Continuing the script from Antonio, you may add a folder chooser either with powershell or CScript.

CScript is faster, but IMHO powershell is easier to work with.

Code: Select all

@echo off
setlocal EnableDelayedExpansion

set "_folder1_=" & set "_folder2_="

if "%~1" neq "" set "_folder1_=%~1"
if "%~2" neq "" set "_folder2_=%~2"

echo CompDirs.bat dir1 dir2
echo/
echo Compare files in both directories

rem Folder chooser with Powershell (slow)
if not defined _folder1_ call :folderSelection "%_folder1_%", _folder1_, "Select first folder"
if not defined _folder2_ call :folderSelection "%_folder2_%", _folder2_, "Select second folder"
rem Folder chooser with CScript (fast)
rem if not defined _folder1_ call :folderSelectionFast _folder1_, "Select first folder"
rem if not defined _folder2_ call :folderSelectionFast _folder2_, "Select second folder"

echo first dir:  %_folder1_%
echo second dir: %_folder2_%
echo/
if not defined _folder1_ if not defined _folder2_ goto :eof

:begin

rem Populate first tree
pushd "%_folder1_%" 2>NUL || (echo First directory not found & goto :EOF)
for /R %%a in (*.*) do (
   set "name=%%~a"
   set "file1["!name:*%cd%\=!"]=1"
)

rem Populate second tree and report files in both trees
popd
cd "%_folder2_%" 2>NUL || (echo Second directory not found & goto :EOF)
echo Files in both directories:
echo/
for /R %%a in (*.*) do (
   set "name=%%~a"
   set "name=!name:*%cd%\=!"
   if defined file1["!name!"] (
      echo !name!
      set "file1["!name!"]="
   ) else (
      set "file2["!name!"]=1"
   )
)
echo/
echo/

echo Files only in %_folder1_%
echo/
for /F "tokens=2 delims=[]" %%a in ('set file1[ 2^>NUL') do echo %%~a
echo/
echo/

echo Files only in %_folder2_%
echo/
for /F "tokens=2 delims=[]" %%a in ('set file2[ 2^>NUL') do echo %%~a

exit/B


rem Powershell folder chooser

CScript is faster, but IMHO powershell is easier to work with.

Code: Select all

snip

Well, IMHO JScript is much easier than PowerShell! The version below use the same WSH BrowseForFolder method, but it only requires two JScript lines instead of the several ones for VBS.

I also added to this version the detection of duplicate files in the same directory.

Code: Select all

@echo off
setlocal EnableDelayedExpansion

if "%~2" neq "" set "folder1=%~1" & set "folder2=%~2" & goto begin

 > folder.js echo var folder = (new ActiveXObject("Shell.Application")).BrowseForFolder(0, WScript.Arguments(0), 0x340, 0x05 );
>> folder.js echo WSH.Echo(folder ? folder.self.path : "");

for /F "delims=" %%a in ('cscript //nologo folder.js "Select first directory"') do set "folder1=%%a"
if not defined folder1 goto :EOF
for /F "delims=" %%a in ('cscript //nologo folder.js "Select second directory"') do set "folder2=%%a"
if not defined folder2 goto :EOF

:begin

rem Populate first tree
pushd "%folder1%" 2>NUL || (echo First directory not found & goto :EOF)
for /R %%a in (*.*) do (
   set "name=%%~a"
   set "tree1["!name:*%cd%\=!"]=1"
   if not defined file1["%%~NXa"] (
      set "file1["%%~NXa"]="%%~Pa""
   ) else (
      set "dup1["%%~NXa"]=1"
      set "file1["%%~NXa"]=!file1["%%~NXa"]! "%%~Pa""
   )
)


rem Populate second tree and report files in both trees
popd
cd "%folder2%" 2>NUL || (echo Second directory not found & goto :EOF)
echo Files in both directories:
echo/
for /R %%a in (*.*) do (
   set "name=%%~a"
   set "name=!name:*%cd%\=!"
   if defined tree1["!name!"] (
      echo !name!
      set "tree1["!name!"]="
   ) else (
      set "tree2["!name!"]=1"
   )
   if not defined file2["%%~NXa"] (
      set "file2["%%~NXa"]="%%~Pa""
   ) else (
      set "dup2["%%~NXa"]=1"
      set "file2["%%~NXa"]=!file1["%%~NXa"]! "%%~Pa""
   )
)
echo/
echo/

echo Files only in "%folder1%":
echo/
for /F "tokens=2 delims=[]" %%a in ('set tree1[ 2^>NUL') do echo %%~a
echo/
echo/

echo Files only in "%folder2%":
echo/
for /F "tokens=2 delims=[]" %%a in ('set tree2[ 2^>NUL') do echo %%~a
echo/
echo/

echo Duplicate files in "%folder1%":
echo/
for /F "tokens=2 delims=[]" %%a in ('set dup1[ 2^>NUL') do (
   echo %%a  file duplicate in folders:
   for %%b in (!file1[%%a]!) do echo     %%~b
)
echo/
echo/

echo Duplicate files in "%folder2%":
echo/
for /F "tokens=2 delims=[]" %%a in ('set dup2[ 2^>NUL') do (
   echo %%a  file duplicate in folders:
   for %%b in (!file2[%%a]!) do echo     %%~b
)

The default start folder for directory selection is "My Documents", that is specified by 0x05 value in fourth parameter of BrowseForFolder method. You may also use 0x11 for "All drives" or 0 for "Desktop"; further details at this site.

Try my dirc.exe tool, available in SysTools.zip there:
https://github.com/JFLarvoire/SysToolsLib/releases
It's written in C, fast, supports any Unicode pathnames in any code page, long pathnames > 260 characters, junctions, symlinks, etc.
There are also many options for refining the comparison. Use option -? to display a help screen.

For example the -b option limits the output to files that are present in both directories:
