Unlike the “normal” folders that are probably scattered all over your desktop, a RAR file needs special software to open it. RAR files can also be split into multiple smaller parts, making it easier to store and transfer large files.

It’s a compressed archive file that holds other files or folders inside it (like a data “container”) in a compressed format to save space. A RAR file is like a digital version of these.

They’re great for storage and because they’re stackable, they save space too. You know those plastic containers that contain lots of smaller containers? You probably have a load stacked in a kitchen cupboard at home (with missing lids).
