Rename file extension with PowerShell

  • Artikel

Last week I ended up finding that one of my directories of pictures lost their file extensions – so I thought I’d spin up PowerShell in Win8 and see if I could remember how to do. Smile 

After a little trial and error I ended up with the following PowerShell Script – reminded me how powerful and easy PowerShell is for scripting all of Windows.

  1. $proj_files = Get-ChildItem | Where-Object {$_.Extension -ne ".jpg"}
  2. ForEach ($file in $proj_files) {
  3. $filenew = $file.Name + ".jpg"
  4. Rename-Item $file $filenew
  5. }
