To expand file content with PowerShell, you can use the Add-Content cmdlet.First, you need to read the content of the file by using the Get-Content cmdlet and store it in a variable. Then, you can use the Add-Content cmdlet to append or insert additional content to the file.For example, if you want to add the text "Hello World" to a file named "example.txt", you can use the following commands:$content = Get-Content -Path .\example.txt
Add-Content -Path .\example.
