Every Computer File System Explained in 13 Minutes!

Your storage drive has no idea what a "file" is — it only understands ones and zeros, and a file system is the invisible rulebook that turns that raw data into the organized folders, photos, and programs you see on screen. This breakdown walks through every major file system ever used in personal computing, from FAT12 on 1977 floppy disks all the way to ZFS on modern servers that can detect and repair silent data corruption on their own. Each file system gets explained through what it actually does differently under the hood — why FAT32 chokes on files over 4GB, how APFS duplicates a 20GB video instantly without copying a single byte, why Linux's EXT4 became the quiet default on billions of devices including Android phones, and what makes ZFS the only file system that fights back against bit rot. Whether you've ever wondered why your USB drive won't work on a Mac or which format to pick for your external drive, every answer is here. ----------------------------------------------------------------- #FileSystems #ComputerScience #TechExplained
