How do I show file extensions?

I've just 'upgraded' to Windows 10 from Windows 7.

I've noticed that file extensions are not shown when I display the files in a folder. For example I have a folder containing html files, and all that appears is e.g. Chapter00 when it should show Chapter00.html, ebook shows when it should show ebook.css, content shows when it should show content.opf, and Jane Eyre shows when it should show Jane Eyre.epub. Strangely enough toc.ncx shows as it should.

I've been through all the settings folders I can think of. How do I make Windows 10 show the file extensions as they were shown in Windows 7?

Hello Alex, and welcome to windowssh blog.

You could use an option in the tutorial below to show known file extensions. It's for Windows 8.1, but it's the same in Windows 10.

Thanks for the welcome, but I'm afraid I can't use your response. I have never used Window 8, and have no idea if there is a ribbon in Windows 10 or where to find it. I'm not even sure where the 'start button' is in Windows 10; is it the window icon on the far left of the task bar?

I'm sorry to be a nuisance, but really must ask you to do a detailed list like:
- Click on start button
- click on {whatever I should do next, and so on}

I'm afraid my knowledge of computers is very limited.

Hi Alex

If you click on the yellow folder button (File Explorer) which is next to the start button.

When it opens, click on the view menu which is at the top.

You should then see a check box for File name extensions. Select that

Thanks. I have it done now.

Great news.

And we might all ask why MS persists with the inconvenient and unsafe practice of hiding extensions.

It's been that way since at least Vista.

They're actually hidden to prevent users from mistakenly renaming the file extension and breaking it's association.

And also to fool people into clicking exe files

I would always recommend that folks don't click on or open a file that they didn't know what it was.
