CMD list folders and file sizes, find the largest folders and files

Quite often we need to check which folder is taking the most space, here is one a line cmd command to do this:

List folders from the smallest to the largest

cmd /v /c "set zeropad=000,000,000,000,000,&for /f "delims=" %a in ('dir /ad /b') do @set bytes=!zeropad!000&(for /f "tokens=3" %b in ('dir /s "%a" 2^>NUL ^| find "File(s)"') do @set bytes=%b)& @for /f "tokens=1* delims=," %c in ('echo !bytes!') do @(set bytes=%c&@set bytes=000!bytes!&@set bytes=!bytes:~-3!& @set bytes=!zeropad!!bytes!&if "%d" NEQ "" set bytes=!bytes!,%d) & @echo !bytes:~-23! %a" | sort

List folders from the largest to the smallest

cmd /v /c "set zeropad=000,000,000,000,000,&for /f "delims=" %a in ('dir /ad /b') do @set bytes=!zeropad!000&(for /f "tokens=3" %b in ('dir /s "%a" 2^>NUL ^| find "File(s)"') do @set bytes=%b)& @for /f "tokens=1* delims=," %c in ('echo !bytes!') do @(set bytes=%c&@set bytes=000!bytes!&@set bytes=!bytes:~-3!& @set bytes=!zeropad!!bytes!&if "%d" NEQ "" set bytes=!bytes!,%d) & @echo !bytes:~-23! %a" | sort /R

 

And if you need both files and folders from the smallest to the largest

cmd /v /c "set zeropad=000,000,000,000,000,&for /f "tokens=4* delims= " %a in ('dir ^| find "/" ^| findstr /E /V /R "DIR^>[ ][ ]*\.\.$ DIR^>[ ][ ]*\.$"') do @set bytes=!zeropad!000&(if "%a" EQU "^<DIR^>" (for /f "tokens=3" %c in ('dir /s "%b" 2^>NUL ^| find "File(s)"') do @set bytes=%c)) & (if "%a" NEQ "^<DIR^>" (set bytes=%a)) & (for /f "tokens=1* delims=," %d in ('echo !bytes!') do @set bytes=%d&@set bytes=000!bytes!&@set bytes=!bytes:~-3!& @set bytes=!zeropad!!bytes!&if "%e" NEQ "" set bytes=!bytes!,%e)& echo !bytes:~-23! %b" | sort

And files and folders from the largest to the smallest

cmd /v /c "set zeropad=000,000,000,000,000,&for /f "tokens=4* delims= " %a in ('dir ^| find "/" ^| findstr /E /V /R "DIR^>[ ][ ]*\.\.$ DIR^>[ ][ ]*\.$"') do @set bytes=!zeropad!000&(if "%a" EQU "^<DIR^>" (for /f "tokens=3" %c in ('dir /s "%b" 2^>NUL ^| find "File(s)"') do @set bytes=%c)) & (if "%a" NEQ "^<DIR^>" (set bytes=%a)) & (for /f "tokens=1* delims=," %d in ('echo !bytes!') do @set bytes=%d&@set bytes=000!bytes!&@set bytes=!bytes:~-3!& @set bytes=!zeropad!!bytes!&if "%e" NEQ "" set bytes=!bytes!,%e)& echo !bytes:~-23! %b" | sort /R
