Delete Long File Names in Windows

longKill.ps1

[CmdletBinding()]
param (
	[Parameter(Mandatory=$True, Position=1)]
	$Filter

$batFileContent = @"
mkdir a
robocopy a %1 /s /mir
rmdir a
rmdir %1
"@

$batFileName = "long.bat"

if (-not (Test-Path $batFileName)) {
	$batFileContent | Out-File $batFileName -Encoding ascii
}

Get-ChildItem $Filter | ForEach { ./long.bat $_.FullName | Write-Output }

if (Test-Path $batFileName) {
	Remove-Item $batFileName
}

This is a simple script for deleting files with names too long for windows to normally delete. My buildserver has folders in the format 100.tcbuildid, 101.tcbuildid, 102.tcbuildid, etc.... so I can easily clean the bad files out using this command like so:

./longKill.ps1 10*.tcbuildid
