So I was trying to figure out why I couldn't read a file called GLOBAL.help despite the file clearly existing in the direction where it was.
So I made a file called global.txt on D:\ and wrote a single letter to it.
$exists("D:\global.txt") = $false
$lines("D:\global.txt") = 0
Renamed it to globa.txt
$exists("D:\globa.txt") = $true
$lines("D:\globa.txt") = 1
