MS-DOS

= SUMMARY =

At no time does Word record the state of the File Allocation Table (FAT). Each time disk Input/Output (I/O) is required, Word looks at the FAT through high-level DOS calls.

This method is slightly slower then recording a “snapshot” of the FAT at program load time for reference during later disk I/O tasks; however, it is far safer from the standpoint of maintaining an accurate picture of the system’s disks. High-level DOS calls are used to avoid BIOS-level inconsistencies between computers.
