Inotify is like a magic ear that listens to changes happening to files and folders on your computer. Whenever something changes, like a file being created or deleted, the magic ear hears it and lets your computer know. This is really helpful for programs that need to know when changes happen, like a music player that needs to know when you add new songs to a folder. Inotify helps these programs keep track of everything that's going on and react to changes quickly. Think of it like a superhero power for your computer!
