function Show-DbaServerFileSystem {
    <#
  .SYNOPSIS
   Shows file system on remote SQL Server in a local GUI and returns the selected directory name
    
  .DESCRIPTION
   Similar to the remote file system popup you see when browsing a remote SQL Server in SQL Server Management Studio, this function allows you to traverse the remote SQL Server's file structure.
 
   Show-DbaServerFileSystem uses SQL Management Objects to browse the directories and what you see is limited to the permissions of the account running the command.
    
        .PARAMETER SqlInstance
   The SQL Server whose filesystem you want to view.
         
        .PARAMETER SqlCredential
    Allows you to login to servers using SQL Logins instead of Windows Authentication (AKA Integrated or Trusted). To use:
 
   $cred = Get-Credential, then pass $cred object to the -SqlCredential parameter.
 
   Windows Authentication will be used if SqlCredential is not specified. SQL Server does not accept Windows credentials being passed as credentials.
 
   To connect as a different Windows user, run PowerShell as that user.        
 
  .PARAMETER WhatIf
   If this switch is enabled, no actions are performed but informational messages will be displayed that explain what would happen if the command were to run.
 
  .PARAMETER Confirm
   If this switch is enabled, you will be prompted for confirmation before executing any operations that change state.

  .EXAMPLE
   Show-DbaServerFileSystem -SqlInstance sqlserver2014a
   
   Shows a list of databases using Windows Authentication to connect to the SQL Server. Returns a string of the selected path.
    
  .EXAMPLE
   Show-DbaServerFileSystem -Source sqlserver2014a -SqlCredential $cred
    
   Shows a list of databases using SQL credentials to connect to the SQL Server. Returns a string of the selected path.
