How can I query a temporary PS-Drive while returning files with a name relative to the drive?

Question

I am trying to create a script where I will be searching the file servers for non inherited permissions. I have run into the 260 character limit for file names as a result.

haven't tested, but if you're not opposed to using 'subst' something like this might work for you

function Get-FreeDriveLetter {
    $drives = [io.driveinfo]::getdrives() | % {$_.name[0]}
    $alpha = 65..90 | % { [char]$_ }
    $avail = diff $drives $alpha | select -ExpandProperty inputobject
    $drive = $avail[0] + ':'
    $drive
}

$file = gi 'C:\temp\file.txt'
$fullname = $file.FullName

if ($fullname.length -gt 240) {
    $drive = Get-FreeDriveLetter
    $path = Split-Path $fullname
    subst $drive $path
    $subst = $true
    rv path
    $fullname = Join-Path $drive $(Split-Path $fullname -Leaf)
}

$fullname
