Join-Path PowerShell Cmdlet

Join-Path is a PowerShell cmdlet that combines a base path and a child path into a single one. This is useful for constructing file or directory paths dynamically. The syntax for using Join-Path is:

Join-Path -Path <base path> -ChildPath <child path>

Here's an example of using Join-Path to create a file path:

$directory = "C:\MyFolder"
$filename = "example"
$path = Join-Path -Path $directory -ChildPath "$($filename).txt"

In this example, $directory is the base path, $filename is the child path, and "$($filename).txt" is the desired file extension. Join-Path combines these to create the full file path, which would be "C:\MyFolder\example.txt".
