Enable / View File Extensions in Windows
If you need to see file extensions and can't locate what you are looking for, it is a good idea that the view file name extensions option is enabled; by default, on many versions of Windows, this is not enabled.
From File Explorer:
- Select View.
- If the panel isn't displayed then the small arrow on the right will be pointing down, just click on it to open the panel.
- Check the 'File name extensions' tick box, as displayed on the above image.
This will enable file extensions globally, across all Explorer windows.
