Last time I showed how to split folder paths to just leave the path – no filenames or drive information. What about the opposite task – joining and testing folder paths.
Here’s an example
$basepath = 'C:\Scripts'
$pathsTotest = 'Containers','HyperV', 'NanoServer', 'NoSuchFolder'
$pathsToTest | foreach {
$path = Join-Path -Path $basepath -ChildPath $psitem
Test-Path -Path $path
}
When you run this the paths to test are joined to the base path and then tested.
The output is
True True True False
which isn’t the most informative you’ll ever see.
The output can easily be made more friendly
$basepath = 'C:\Scripts'
$pathsTotest = 'Containers','HyperV', 'NanoServer', 'NoSuchFolder'
$pathsToTest | foreach {
$path = Join-Path -Path $basepath -ChildPath $psitem
$props = @{
Path = $path
Found = Test-Path -Path $path
}
New-Object -TypeName psobject -Property $props
}
Create an object for the output using the full path you’re testing and the result
The output looks like this
Path Found ---- ----- C:\Scripts\Containers True C:\Scripts\HyperV True C:\Scripts\NanoServer True C:\Scripts\NoSuchFolder False
You could save the output as a CSV for later work if required
