Hi Boris,

Thank you very much for your respond.
I copied this script and executed as you specified. But not got any solution.
The following was been displayed in CLI.
C:\>Test.cmd C:\Sample
'selLocal' is not recognized as an internal or external command,
operable program or batch file.
Missing operator.
Missing operator.
Missing operator
....
Size is: !value!

So I put @echo on and the CLI executed as shown below:
C:\>Test.cmd C:\Sample

C:\>selLocal EnableDelayedExpansion
'selLocal' is not recognized as an internal or external command,
operable program or batch file.

C:\>set /a value=0

C:\>FOR /R C:\Sample %I IN (*) DO set /a value=!value!+%~zI

C:\>set /a value=!value!+3064
Missing operator.

C:\>set /a value=!value!+2672
Missing operator.

C:\>set /a value=!value!+6135
Missing operator.

C:\>set /a value=!value!+5
Missing operator.

C:\>set /a value=!value!+2
Missing operator.
Size is: !value!

Please Help me out in this.
Say where I made mistake ?
I need this very urgent. So please...

Hi,

You can do this with a batch file something like this:

@echo off
selLocal EnableDelayedExpansion
set /a value=0
FOR /R %1 %%I IN (*) DO set /a value=!value!+%%~zI
@echo Size is: !value!

HTH

For large directories, it might be better to list in k or Mb to avoid number overflow...

@echo off
setLocal EnableDelayedExpansion
set /a value=0
set /a sum=0
FOR /R %1 %%I IN (*) DO (
set /a value=%%~zI/1024
set /a sum=!sum!+!value!
)
@echo Size is: !sum! k

Great scripts..  anyway could we exclude the folder also?

example: populate size inside %systemroot%\system32\ but exclude folder "drivers".

The original command for doing that on *nix based systems was 'du'. You can get a Win32 port of the GNU file utils from
https://sourceforge.net/projects/unxutils/
https://sourceforge.net/projects/unxutils/

As an example, using the included utils you can get a list of the directory sizes within the current one by running
find . -maxdepth 1 -exec du -sh \"{}\" \;
Sysinternals have released a lesser clone of the *nix version which is available from
https://docs.microsoft.com/en-us/sysinternals/downloads/du
