In W10 desktop, right-click on the
White Windows Logo (used to be the
Start Button in W7), find and click on
File Explorer (used to be
Windows Explorer in W7). Next click on the
VIEW tab. View tab will then show a
Ribbon Bar at the top of the
File Explorer screen. On the far right of the
VIEW Ribbon Bar, you will see 3 checkboxes to the left of the
OPTIONS select box.
You'll notice all 3 boxes are unchecked.
The default in W10 is for System Files to be hidden. Checking the
HIDDEN ITEMS box, brings them back where you can see them again.
You'll also notice the
FILE NAME EXTENSIONS box is unchecked by default in W10;
which means those are turned off when you start W10. To enable or turn them on so you can see them, you simply click on the checkbox to turn them on so you can see them. In your case, you just leave that box unchecked (default) and you'll never see them.
On that same
VIEW Ribbon Bar, on the far right end, you'll see the
OPTIONS select box. You can click on the drop-down arrow and you'll see a small menu; you can click on the first item
CHANGE FOLDER AND SEARCH OPTIONS, which brings up the
FILE OPTIONS box, click the 2nd tab, the
VIEW tab, and you can scroll through the
ADVANCED SETTINGS options and get more granular selections of how your files are displayed. The checkboxes in that list do the same thing the checkboxes do on the
VIEW Ribbon Bar, but provide you with a few more special options which you shouldn't need most of the time. The first 2 paragraphs above explaining the 2 checkboxes on the
VIEW Ribbon Bar, will take care of the questions you asked in your Post. There are a few more that might prove useful so that's why I mention it to you.
Enjoy!
