I am not sure if it's possible, i have kind of zero idea to create powershell script. it will be really helpful for me if someone can help me.


I have multiple sub folders, lets say

Code: 
C:\test\1
C:\test\2
C:\test\3

inside the folder there is multiple image files. i want to list the sub folder file name and size and save text files inside the folders.

Code: 
C:\test\1\filelist.txt
C:\test\2\filelist.txt
C:\test\3\filelist.txt

filelist.txt will have something like this

Code: 
logo.png  30kb
Header.png 4MB

here one sample script i found, wondering if some can help


Code: 
$Folder = 'C:\pic'
$Output = 'C:\output.txt'
$Files = Get-ChildItem -Path $Folder -Filter *.mp4 -File
$objShell = New-Object -ComObject Shell.Application
$objFolder = $objShell.Namespace($Folder)
foreach( $File in $Files ) {
    $objFile = $objFolder.ParseName($File)
    $Name = $objFolder.GetDetailsOf($objFile, 0)
    $Size = $objFolder.GetDetailsOf($objFile, 1)
    $Length = $objFolder.GetDetailsOf($objFile, 27)
    $Tab = [char]9
    "$Name$Tab$Size$Tab$Length" | Out-File -Append -FilePath $Output
}

Just put it C:\test\1\ in your browser URL (chrome, firefox) and you get all listed size, format

will do for you?

Why mess with the garbage that is Powershell when you can do it in Python and run it anywhere:

Python: 
#!/usr/bin/env python3

import os


ROOT_FOLDER = r'C:\target_folder'
INDEX_FILENAME = 'filelist.txt'


def get_file_name_and_size(filename, column_width):
    file_size = float(os.path.getsize(filename))
    units = ('B', 'KB', 'MB', 'GB', 'TB', 'PB')
    order, limit = 0, len(units) - 1
    while file_size >= 1024 and order < limit:
        order += 1
        file_size /= 1024
    name = os.path.basename(filename).ljust(column_width)
    return f'{name} {round(file_size)} {units[order]}'


def create_index_text(path):
    folder, sub_folders, sub_files = next(os.walk(path))
    column_width = max(len(fn) for fn in sub_files) if sub_files else 0
    return '\n'.join([
        get_file_name_and_size(os.path.join(path, filename), column_width)
        for filename in sub_files
        if filename != INDEX_FILENAME
    ])


def main():
    print(f'Scanning folder: {ROOT_FOLDER}')
    for sub_folder_name in os.listdir(ROOT_FOLDER):
        path = os.path.join(ROOT_FOLDER, sub_folder_name)
        if os.path.isdir(path):
            print(f'Processing folder: {path}')
            index_txt = create_index_text(path)
            if index_txt:
                filename = os.path.join(path, INDEX_FILENAME)
                with open(filename, 'w') as stream:
                    stream.write(index_txt)
                print(f'Saved file: {filename}')
    print('All done.')


if __name__ == 'main':
    main()

This will list it in a column as well instead of separating file name and size with a single tab.

Click to expand...
windows give file size in bytes which is not good for human eyes
