Your problem here is with win32 not powershell I suspect. Your script would probably have worked with powershell on Linux, but windows you need to use UNC paths to get a 2^16 - ~20 character path limit rather than the 256 character path limit of regular paths. Or there's some registry hacks to remove the limit from regular paths.
