Show and hide file extensions in Windows 10

by on

Introduction

In Microsoft Windows 10, the file extensions of known file types that are associated with some software installed in your computer, are hidden.

This is due to Microsoft's policy which makes it somewhat easier for common users, but at the same time may also be potentially dangerous due security reasons.

Microsoft prefers simplicity over security, but that means that dangerous and harmful files can be hidden under wrong file type and users does not have fully under control what they opens.

More advanced users of Windows 10 who want to keep their files and data under control can turn off "Hide extensions for known file types" File Explorer feature.
