Renaming Files in a Folder using PowerShell

In this article, we will explore how to use PowerShell to batch rename files in a folder. PowerShell is a powerful command-line tool that allows you to automate repetitive tasks and manage your files and folders with ease. We will cover the key concepts and provide detailed instructions on how to rename files in a folder using PowerShell.

Prerequisites

Before we begin, make sure you have the following:

• A Windows operating system with PowerShell installed.
• A folder containing files that you want to rename.

Renaming Files using PowerShell

To rename files in a folder using PowerShell, follow these steps:

1. Open PowerShell and navigate to the folder containing the files you want to rename.
2. Use the Get-ChildItem cmdlet to retrieve a list of files in the folder.
3. Use a loop to iterate through each file and rename it using the Rename-Item cmdlet.

Example

Let's say you have a folder containing several image files with the file extension .jpg, and you want to rename them with a prefix of "img-".

# Navigate to the folder containing the files
cd C:\path\to\folder

# Get a list of all .jpg files in the folder
$jpgFiles = Get-ChildItem -Filter *.jpg

# Iterate through each file and rename it
foreach ($file in $jpgFiles) {
    # Rename the file with a prefix of "img-"
    Rename-Item -Path $file.FullName -NewName "img-$($file.Name)"
}

Key Concepts

• Get-ChildItem: This cmdlet retrieves a list of items (files, folders, etc.) in a specified location.
• Rename-Item: This cmdlet renames an item.
• foreach: This loop iterates through each item in a collection.
• $file.FullName and $file.Name: These properties contain the full path and name of the file, respectively.
• "img-$($file.Name)": This string concatenates the prefix "img-" with the original file name.
