ELI5: Explain Like I'm 5

File viewer

Imagine you have a bunch of pictures, like drawings or photos, or even documents with words on them, in a big folder. A file viewer is like a special pair of glasses that you can put on to look at those pictures or documents without actually opening them up.

The file viewer helps you look at the things in the folder without having to open them one by one. It shows you a little preview of what's inside each file, so you can quickly pick which one you want to open up and see more of.

It's like a little helper that makes it easier for you to find things in your big folder full of files. So instead of having to open every file to figure out what's inside, the file viewer helps you take a sneak peak, so you know which one to pick without actually opening it up.
