I understand for simplicity for the mom and pop that don’t care about file extensions. I for one always turn them back on. One because I sometimes need to make a specific file type, example make a registry file, and two it lowers the risk making a stupid mistake and clicking SomeCoolFamilyVideo.m4v when it fact it is SomeCoolFamilyVideo.m4v.exe and now you are dealing with a virus.
In windows 8 is pretty easy to turn on ‘File name extensions’ To do this:
- Open windows explorer
- Click the pointing down carrot on the right side to expand the menu
- Then Click on View
- Place a check on ‘File name extensions’
- All done and you should now see the file extensions.
