file size via cmd/bat or vbs in terms of MBs

What are you trying to accomplish?  If you are trying to get a list of all files on the hard drive within all folders, you can open an administrative command prompt and issue the following command.

dir /a /s /os

/a --> Show all files
/s --> Show files in all subfolders
/os --> Order the files by size (can also use /o-s)

Is that what you are needing?

If you want, you can write that out to a file by changing it to

dir /a /s /os > c:\dirList.txt

There is a portable tree size util which can run without installing afaik.  If you want batch or VBScript I have a few batches that may be of use here, e.g. second two show you the biggest 20 files in a directory and subdirs you choose, first one total size in subdir.

You can sort files by size but only in one dir from a dir command.  If you add /s it will sort them within each dir.

dir /o-s

If you really want to you can get a CSV file of any directory structure of all files with something like this which you could put in excel etc:

@echo off
pushd c:\startdir
for /f "tokens=*" %%F in ('dir /b /a-d /s') do echo "%%~dpF","%%~fxF",%%~zF > "%userprofile%\desktop\file-list.csv"
popd
start "" "%userprofile%\desktop\file-list.csv"

Powershell if OK gives other options

A 3rd party program is out of question but i will give a try for the script. My aim is to see sorted files and folders w.r.t size

Hi;

I used;

@echo off
pushd c:\startdir
for /f "tokens=*" %%F in ('dir /b /a-d /s') do echo "%%~dpF","%%~fxF",%%~zF > "%userprofile%\desktop\file-list.csv"
popd
start "" "%userprofile%\desktop\file-list.csv"

to use it I created a startdir directory as it was giving an error on line 2. I also created file-list.csv but now it gives file not found error on console. Am i missing something?

Regards.

Sorry I should have said the "pushd" line was to take it to the directory under which you wanted the info.  If you want the whole C: drive then it is going to make you a file with one line per file on the whole dir.  If you wan that change the line to

pushd c:\

Hi Steve;

Seems fine except for the bytes. I want to have it MB and I added the /1048576 but it is treated as string. Any remedy?

Regards.

Another way since we are talking Excel... if that is acceptable a few lines of VBA could scan down a directory structure and populate a spreadsheet for you.  Say what you are after and will see what I can knock up.

if you do want to look at other ways just say... exceand macros in vba is great way of finding info and presenting it...
