How to Rename Using Powershell?

To rename a file or folder using PowerShell, you can use the Rename-Item cmdlet.

1. Open PowerShell by searching for it in the Start menu and opening the application.
2. Navigate to the directory where the file or folder you want to rename is located using the cd command.
3. Use the Rename-Item cmdlet followed by the current name of the file or folder and the new name you want to give it. For example, to rename a file called "oldfile.txt" to "newfile.txt", you would use the command: Rename-Item oldfile.txt newfile.txt

What is the process for renaming files in bulk using PowerShell?

To rename files in bulk using PowerShell, you can follow these steps:

1. Open PowerShell by searching for it in the Start menu and clicking on the result.
2. Navigate to the directory where the files you want to rename are located using the cd command. For example, if the files are in a folder called "Documents" on your desktop, you would type cd C:\Users\YourUsername\Desktop\Documents.
3. Use the Get-ChildItem command to get a list of all the files in the directory. For example, you can use Get-ChildItem -File to list only files (excluding directories). You can add other parameters to filter the list as needed.
4. Use a loop to iterate through each file and rename it using the Rename-Item command. For example, you can use a foreach loop like this:

1
2
3
4

foreach ($file in Get-ChildItem) {
    $newName = $file.Name -replace "oldtext", "newtext"  # replace "oldtext" with the text you want to replace and "newtext" with the new text
    Rename-Item -Path $file.FullName -NewName $newName
}

1. Run the script by pressing Enter. This will rename all the files in the directory that match the criteria you specified.

Make sure to test the script on a small number of files first to ensure it works as expected before running it on a large number of files. Also, be careful when renaming files in bulk as it can be difficult to undo the changes.

How to rename a file with a specific extension in PowerShell?
