title: Powershell Get-ChildItem : The specified path, file name, or both are too long.
body: <p>My script giving error "Get-ChildItem : The specified path, file name, or both are too long. The fully qualified file name must be less than 260 characters, and the directory name must be 
  less than 248 characters." and "Measure-Object : The property "length" cannot be found in the input for any objects".
  It supposed to create a text file with list of folders arranged by size. However,I get errors above and some folders get size 0.0 Mb. Do you have any suggestions? </p>
