PowerShell script to generate a Rainmeter skin

I recently discovered Rainmeter, a desktop customization tool that lets you use some really nice looking gadgets. I wanted a simple skin to show disk free space.

I have five volumes, I could have manually written a custom skin. (Rainmeter skins are INI files.) That would involve setting a measure section for each disk and a in another section define how the output looks. Or I could take the much more time consuming task of writing a PowerShell script to iterate through my disks and write the skin INI file.

The body of the script:

# Stop on the first error
$ErrorActionPreference = "Stop"

$RainmeterPath = [environment]::getfolderpath("mydocuments") + "\Rainmeter\Skins\"
$SkinName = "Kenward"
$FileName = "disks.ini"

If (-Not (Test-Path $($RainmeterPath + $SkinName))) {
    Set-Location $RainmeterPath
    mkdir $SkinName
    }

$OutFile = $RainmeterPath + $SkinName + "\" + $FileName
$Disks = Get-Volume | where {$_.DriveType -eq "Fixed"} | sort -Property DriveLetter
$Disks

$Header = @"
