title: Powershell Move-Item Rename If File Exists
body: <p>I have a powershell script that takes all of the files in one directory, renames the first one and moves it, and then goes to the next file. Sometimes there will be multiple files that get renamed to the same name (because of the system that it's going to, not ideal and will have to change) and was overwriting files that shouldn't have been getting overwritten with -force. I need all of the files to move but also have unique names so we have them available in the destination location. Is there an easy way to have it automatically rename so it would look like:</p>
  
  <p>123.txt
  123(1).txt
  123(2).txt</p>
  
  <p>or</p>
  
  <p>123.txt
  123_1.txt
  123_2.txt</p>
