What does the "Show File Extensions & Change What Opens Your Files" guide cover?

Show hidden file extensions in File Explorer, change file associations, rename file types, and learn to identify dangerous file extensions for security.

What causes this and what does the fix involve?

Can't tell what type your files are? This beginner guide shows how to reveal file extensions, change which app opens each type, and spot dangerous files.

Why does Windows hide file extensions by default?

Mostly to make file names look cleaner and less technical — the extension is still there and still doing its job, it's just not shown to you unless you choose to see it.

Is it unsafe that extensions are hidden?

It's a minor safety trade-off — a hidden extension makes it slightly easier for a disguised file to look like something it isn't, which is one good reason to be able to see them.

What decides which app opens a file when I double-click it?

The file's extension, matched against a list Windows keeps of which app is set to handle each type — that pairing is exactly what determines the app that opens.

Can I choose a different app to open a certain file type?

Yes — that pairing between file type and app is something you have control over, not a fixed, unchangeable setting.

Will seeing extensions change how my files behave?

No — it only changes what you can see, not what the files actually are or how they work underneath.
