Below is my program for comparing files in two folders. It works well if no space character exists in folder names. But if there is a space in folder name, it goes wrong from loop of "FOR /d %%H in (*) DO ". I tested this program with c:\av1\11 vs c:\av1\22. There is a sub-folder "kk yy" under c:\av1\11.
In case of "kk yy" being empty, after showing "files done, then subdir", it shows
"to compare %~fH :::: c:\av1\22\kk yy\%~nxH"
"The follwing usage of the path operator in batch-parameter substitution is invalid: %~fH" "C:\av1\22\kk yy\%~nxH"
In my opinion, it shouldn't show "to compare ...." for folder "kk yy" is empty. No any iteration should be executed, I think.

In case of "kk yy" containing a file "0000", it shows
"c:\av1\11\kk yy\0000 ++++ c:\av1\22\kk yy\0000
"The system cannot find the path specified"

Is there any way to conquer the issue from folder containing SPACES?


:cmpdir dir1 dir2
setlocal enabledelayedexpansion

@echo on
pushd %2
@echo off

for /f "delims=" %%A in ('cd') do set dir2=%%A
popd

echo %1 ***vs*** %2

pushd %1
echo to compare file first
FOR %%G in (*) DO (
echo file: %%G
echo %%~fG ++++ %dir2%\%%~nxG
if not exist %dir2%\%%~nxG (
echo file %dir2%\%%~nxG disappeared
goto :cmpdir_err
)
fc /b **~fG %dir2%\**~nxG > nul
if !ERRORLEVEL! neq 0 (
echo file %dir2%\%%~nxG corrupted
goto :cmpdir_err
)
)
echo files done, then subdir
FOR /d %%H in (*) DO (
echo === to enter %%~fH
if not exist %dir2%\%%~nxH (
echo folder %dir2%\%%~nxH disappeared
exit /b 255
)
echo to compare %%~fH :::: %dir2%\%%~nxH
call :cmpdir "%%~fH" "%dir2%\%%~nxH"
if !errorlevel! equ 255 goto :cmpdir_err
)
:cmpdir_ok
popd
exit /b 0

:cmpdir_err
popd
exit /b 255Try putting the file names in quotes.It doesn't work.
