Here is a quick little tweak you can do that will take off or add the file extension from any folder you open. That is, you can make the file extension visable/hidden so you can see (or not) what extention the file has (eg. jpg, zip, wmv). Just follow these points and you will be able to do it easy;

  • Open a folder up to whatever one you want
  • Click tools (you may need to press alt first)
  • Open folder options
  • Go to the view tab
  • Either check or uncheck ‘hide extensions for known file types’
  • Click apply and OK
  • You will now either see the extension shown or hidden
