➤ How to batch rename files with Windows PowerShell command script details

To invoke Windows PowerShell in Windows, you can type

‘powershell’

in the search box. Using the Run dialog

(Windows + R)

you can also type-in the same ‘powershell’ command. For ease of use in Windows 7, you can open it by clicking Accessories in the Start Menu, then hit PowerShell. For Windows 8.1 or 10, look for the Windows PowerShell folder then hit the PowerShell executable.

Note: You can also rename your files in bulk using the old-reliable MS-DOS command-line. To rename files in Windows using CMD, you can either use ‘ren’ or ‘rename’ then use * and ? for wildcards and file matching. However, this article focuses mainly on Windows PowerShell and it’s ability to perform complex tasks such as batch file renaming.

First off, change your directory to where the files are located by using the ‘Set-Location -Path’ command:

Set-Location -Path C:\

You can change the path to your desired folder for example:

Set-Location -Path C:\Users\your_username\Desktop

Although changing to another drive is a much faster route. Just type in the desired drive letter. Let’s say from drive ‘D:\’ you change it to ‘C:\’

C:\

Tip: Make sure to enclose the path in quotes if they contain spaces.

After setting your desired folder where the files are residing, complete the batch file renaming process by using the script below:

$filter = ‘*.png’
get-childitem -path $path -filter $filter | rename-item -newname {$_.name -replace ‘old_name’,’new_name’}

This is assuming that ‘.png’ is your file type. You can modify this to your desired file type such as ‘.mp3’, ‘.jpg’ or ‘.bmp’. Finally, change the ‘old_name’ and ‘new_name’ as intended. In our example, we used ‘terablitz_old_name_’ and changed it to ‘terablitz_new_name_’.
