windows - The Directory name is too long in batch

I already asked the question in stack overflow, but did not get any answer from anyone. So i am asking the same question here also.

I am trying make a program which will calculate size of all folder present in the specified location or the current location using a batch script and i am writing it into a .csv file

I followed this question in stackoverflow

https://stackoverflow.com/questions/21711180/how-to-list-all-folder-with-size-via-batch-file

and my code is

`@echo off
 setlocal disabledelayedexpansion
 set "folder=%~1"
 Set "Value=0"
 if not defined folder set "folder=%cd%"
  (for /d %%a in ("%folder%\*") do (
    set "size=0"
    for /f "tokens=3,5" %%b in ('dir /-c /a /w /s /x "%%~fa\*" ^| findstr /b /c:"  "')do if "%%~c"=="" set "size=%%~b"
   setlocal enabledelayedexpansion
   echo(%%~nxa , !size!
   endlocal
  ))>>foldersize.csv 
endlocal
exit /b`

When i run the code, i am getting an error

The directory name "dir_name" is too long

I already knew that the maximum length for a windows path name is 260 character and that might be the reason for this error.

Is there any way I can solve this problem ??

Thanks in advance for every response.
