ELI5: Explain Like I'm 5

Reiserfsprogs

Okay, so imagine you have a toy box full of different kinds of toys - blocks, dolls, cars, and more. Now, you have to put all the toys in order so that you can find them easily whenever you want to play with them.

Reiserfsprogs is like a big rulebook that helps your computer put all the files and information on your hard drive in order. It helps your computer keep track of where everything is, so that the computer can find it quickly when you need it.

Just like you can easily find your favorite toy car in your toy box because you know where it is, reiserfsprogs helps your computer quickly find the files you want to use.
