File archiver

A file archiver is like a magic box that can hold many things inside it. Just like how you can put your toys in a toy box, a file archiver can put many computer files inside it.

When you want to use the files that are inside the archiver, you have to open it up and take them out. This is kind of like when you want to play with your toys, you have to open up the toy box and take them out.

Archiving files is helpful because it can make them take up less space and it can also protect them from being harmed by things like viruses. It's like how you might put your toys in a box to keep them safe and out of the way.
