For a Windows or Mac user the filesystem is something they will probably never think about in their daily computing adventures. That is mostly because there really isn’t a choice in the matter. As a Windows user the only time I actually have to worry about the filesystem is when I’m formatting a USB drive. For my hard drives the choices are NTFS, NTFS, and.. oh yeah NTFS. My earliest recollection of what a filesystem is happened when my Windows 98 machine had crashed and I had to wait while the machine forced a filesystem check on the next start up. More recently FAT32 has gotten in my way with it’s 4GB file size limitation.
