+    .SYNOPSIS
+    Lists the content of a folder and supports long path names (>256 characters)
+
+    .DESCRIPTION
+    Uses the Microsoft.Experimental.IO assembly to list folder contents without
+    path name length limitations. You can use this function to search for and identify 
+    files and folders that use long path names.
+
+    .EXAMPLE
+    Get-PSOneDirectory -Path C:\Windows -ErrorAction SilentlyContinue
+    Dumps the entire content of the windows folder and reports all files
+    and folders and their path length. Error messages due to folders
+    where you have no access permissions are suppressed.
+
+    .EXAMPLE
+    Get-PSOneDirectory -Path C:\Windows -ErrorAction SilentlyContinue |
+      Where-Object PathLength -gt 200
+    Lists files and folders with a path length of greater than 200 characters. 
+    Error messages due to folders where you have no access permissions are suppressed.
