It is a good idea to turn on the ability to see hidden files and extensions on your Windows computer.
First go to Control Panel
Then open File Explorer Options
Go to View – then select the ” Show Hidden Files , Folders and Drives ”
You should also remove the tick from ” Hide Extensions For Known File Types ” – you will then be able to see exactly what type of files you have on your computer or if looking in email attachments , what you may about to run.
