I am using a program called "Easy Context Menu" which allows me to create customized context menus when you right click in File Explorer. I wanted to create my own Context Menu item that allows me to copy a file and it's parenting folder structure into another directory, excluding all of the files in the parented folders.

Example:

target file path: C:thebigfoobar.txt



destination path: D:cow

I want the file 'bar.txt' and it's parenting folders up until 'big' to be copied into the directory 'cow' without the other files in 'big' or 'foo'. The end result should look like:

D:cowbigfoobar.txt

'big' should only contain 'foo' and 'foo' should only contain 'bar.txt'. The program allows me to send the file as a parameter to a file of my choice, in this case a batch file.

I have gotten stuck at the for loop in the ':main" subroutine. It will only print the whole path of the selected file and ignores the delimiter. 'countA' is returned as '1' after the loop and it would have printed the whole path minus drive letter. I do not understand why the for loop is ignoring the delimiter and not separating the path into separate folder names. The reason I am tying to do this is so the user can choose at which point the parented folders should be copied over. This is my first time writing actual code in batch so I still don't completely understand 'setlocal' and a few other things.

I have tried changing the tokens and I am able to choose the individual sections in between the slashes, but I am never able to capture the entire string as separate chunks. I have also changed the delimiter and got the same issue.

@echo off

setlocal

set _target=""

set _dest=""

if not exist %1 goto:error_no_path

set _target=%~pnx1

echo %_target%

goto :dest_selct



:dest_selct

echo select destination folder

pause

set "psCommand="(new-object -COM 'Shell.Application')^

.BrowseForFolder(0,'Please choose destination folder.',0,0).self.path""



for /f "usebackq delims=" %%I in (`powershell %psCommand%`) do set "folder=%%I"



setlocal enabledelayedexpansion

echo You chose %folder%

choice /c ync /n /m "Is this correct? ([Y]es, [N]o, [C]ancel)"

if %ERRORLEVEL% EQU 3 goto:eof

if %ERRORLEVEL% EQU 2 goto:dest_selct

if %ERRORLEVEL% EQU 1 (set _dest="%folder%")&&(goto:main)



:error_no_path

ECHO No file path/name

pause

GOTO:eof



:main

echo main

set _countA=0

echo count starts at %_countA%

for /f "tokens=* delims=" %%F in ("%_target%") do (

    echo token %_countA% is %%F

    echo count is %_countA%

    set var!_countA!=%%F

    set /a countA+=1

)

echo var1: %var1%

echo count is now %countA%

pause

I should have more than one variable at the end, each being the name of a folder that parents the target file and the count should be however many parent folders there are, plus the file itself. What I am actually getting is one variable and it contains the whole target path still.

The for loop does not delimit as you have tokens=*,
which gets all tokens as one token. Leading delimiters are stripped.
Only var0 has a value, not the echoed var1.

To split _target by path segments, use:

for %%F in ("%_target:=" "%") do echo %%~F

Another issue you have is if you choose n at the choice prompt,
the goto:dest_selct will cause setlocal enabledelayedexpansion
to execute again. Since you are not using endlocal, then the
local environment is recursing without ending. Sometimes endlocal
is implied, so you may not need to use it, though not in this case.

Try this fix:

@echo off

setlocal

set "_target="

set "_dest="

if not exist "%~1" goto:error_no_path

set "_target=%~pnx1"

echo %_target%

goto :dest_selct



:dest_selct

echo select destination folder

pause

set "psCommand="(new-object -COM 'Shell.Application')^

.BrowseForFolder(0,'Please choose destination folder.',0,0).self.path""



for /f "usebackq delims=" %%I in (`powershell %psCommand%`) do set "folder=%%I"



echo You chose %folder%

choice /c ync /n /m "Is this correct? ([Y]es, [N]o, [C]ancel)"

if %ERRORLEVEL% EQU 3 goto:eof

if %ERRORLEVEL% EQU 2 goto:dest_selct

if %ERRORLEVEL% EQU 1 (set "_dest=%folder%") && goto:main



:error_no_path

ECHO No file pathname

pause

GOTO:eof



:main

setlocal enabledelayedexpansion

echo main

set "countA=0"

echo count starts at %countA%



rem Remove leading backslash if exist.

if "%_target:~,1%" == "" set "_target=%_target:~1%"



rem Split into path segments.

for %%F in ("%_target:=" "%") do (

    echo token !countA! is %%~F

    echo count is !countA!

    set "var!countA!=%%~F"

    set /a countA+=1

)



echo var1: %var1%



rem Echo all variables starting with var and their values.

set var

echo count is now %countA%

endlocal

pause

• Adjusted double quoting.


• Changed instances of variable name of _countA to countA to match.


• 
  set var to show all variables starting with var for debugging.


• 
  for loop now spilts on path segments.


• Moved setlocal enabledelayedexpansion out of label loop.


• Fix 1st argument check if not defined.

Refer to set /? about variable substitution i.e. "%_target:=" "%", which replaces with " ".
