Manage the XP File Systems
As mentioned, the file system helps the OS interact with fixed storage media. It achieves this by dividing the space on a logical "slice" of physical media into "storage containers." The file system then assigns numbers to these containers and keeps track of which containers store a given file. It also determines how large the containers are and keeps track of which containers are free.Windows XP supports three types of file systems for hard drives: FAT16, FAT32, and NTFS. (It also supports FAT12 and CDFS for floppies and CD-ROMs, respectively, but we won't cover these here because you don't have to manage these file systems.) Each logical drive needs to be formatted with one of these three file systems before use.
What's a Drive Letter, Anyway?Glad you asked. Every primary partition, logical drive of an extended partition, volume on a dynamic disk, and removable disk (such as floppies, CD-ROMs, tape devices, and so on) is assigned a drive letter by default. The drive letters help XP know what file system drivers to "call" when a program requests data from a given location. On typical store-bought, preinstalled computers, the floppy drive is "A," the hard disk is "C," and the CD-ROM is "D."  |
