How to list files and folders using Powershell?

Introduction to file listing using the PowerShell command line tool.

PowerShell is a powerful tool used for executing commands and scripting in Windows environments. You can for example list files using PowerShell for example. While copying files is an essential task, listing files, folders, and subfolders is equally important and can be done using PowerShell’s Get-ChildItem command. This tutorial provides a comprehensive guide on listing files using PowerShell.

1. List files and folders using PowerShell (including subfolders)

Windows PowerShell provides the Get-ChildItem command, allowing you to list files and directories within a specified path. It can be combined with other options and parameters for more complex listing tasks.

1.1 Basic Listing of files in a folder

To list all files and directories in a specific folder:

Get-ChildItem C:\WORK\Folder
List files in a folder using Get-ChildItem PowerShell command
List files in a folder using Get-ChildItem PowerShell command

1.2 List files and filter by extension name

For example, to list only the text files identified with the .txt extension, use the wildcard and the txt in the filter, like in the example below:

Get-ChildItem C:\WORK\Folder -Filter "*.txt"

1.3 Exclude specific items by extension

To exclude some files, use the same principle, as in the previous section, but this time with the Exclude keyword, like the .docx Word documents like below:

Get-ChildItem C:\WORK\Folder -Exclude "*.docx"

2.1 Display the file size with PowerShell

2.2 Get the file extension

You can identify the file type by checking its extension. The script below, for example, will return the extension, in this case it is .jpg.

$file = Get-Item "C:\WORK\Folder\image.jpg"

2.4 Work with files and folders permission

You can manage file permissions using the Get-Acl and Set-Acl cmdlets. Here’s an example of how to retrieve permissions:

$acl = Get-Acl "C:\path\to\file.txt"

3. Combine Get-ChildItem with other PowerShell commands

Combine Get-ChildItem with other cmdlets for more advanced operations. For example, list files and send the list through a pipe to another PS command:

Get-ChildItem C:\WORK\Folder | ForEach-Object { /* Do something with each item */ }
