The file system is the way your computer stores and organizes information on storage devices, such as hard drives or flash drives.
It's like the giant library of your digital life, where all your files and folders are carefully arranged. In fact, it's more like a library than you might think, because just like books, files have names, locations, and metadata that describe them.
Without a file system, your computer wouldn't know how to find the information you need, and you'd be lost in a sea of data. Fortunately, file systems make it easy for you to browse, search, and access your files, and they do so with a touch of magic.
A computer file is a string of bytes that can be any length, from one byte up to all of the bytes available on the disk. This file system gives application programs an easy way of using the disk.
Applications can ask the OS to create, read, write or erase something called a file. You open it, request bytes, send it bytes, make it bigger or smaller, and close the file.
If you ask the OS to look at your disk, it will show you a list of all the file names, and usually their sizes and the date and time when they were last written to.
