Peter navigated to \\corpfs\projects\moldflow\archive\.system . Buried in a folder with a null character name (visible only via PowerShell) was a 14-month-old lock file—. The server’s file system had never cleared the lease because the process that created it had terminated abnormally. Every new Moldflow session since then had politely avoided that file.
