Get Folder Size from Windows Command Line

Question

Is it possible in Windows to get a folder\'s size from the command line without using any 3rd party tool?

I want the same result as you would get when right clicking

Answer 1

So here is a solution for both your requests in the manner you originally asked for. It will give human readability filesize without the filesize limits everyone is experiencing. Compatible with Win Vista or newer. XP only available if Robocopy is installed. Just drop a folder on this batch file or use the better method mentioned below.

@echo off
setlocal enabledelayedexpansion
set "vSearch=Files :"

For %%i in (%*) do (
    set "vSearch=Files :"
    For /l %%M in (1,1,2) do ( 
        for /f "usebackq tokens=3,4 delims= " %%A in (`Robocopy "%%i" "%%i" /E /L /NP /NDL /NFL ^| find "!vSearch!"`) do (
            if /i "%%M"=="1" (
                set "filecount=%%A"
                set "vSearch=Bytes :"
            ) else (
                set "foldersize=%%A%%B"
            )
        )
    )
    echo Folder: %%~nxi FileCount: !filecount! Foldersize: !foldersize!
    REM remove the word "REM" from line below to output to txt file
    REM echo Folder: %%~nxi FileCount: !filecount! Foldersize: !foldersize!>>Folder_FileCountandSize.txt
)
pause

To be able to use this batch file conveniently put it in your SendTo folder. This will allow you to right click a folder or selection of folders, click on the SendTo option, and then select this batch file.

To find the SendTo folder on your computer simplest way is to open up cmd then copy in this line as is.

explorer C:\Users\%username%\AppData\Roaming\Microsoft\Windows\SendTo
