The record

Purpose: DEFRAG optimizes file loading times from a disk by moving file fragments together.
Interface: It provides a menu-driven user interface and a command-line mode selected with the /C option.
Optimization modes: The /F option fully optimizes a drive by placing files at the beginning of the disk without gaps, while /U unfragments files but may leave gaps.
File ordering: The /S option sorts files by name, extension, date and time, or size, with an optional descending order.
Other options: Options include quick defragmentation, rebooting after optimization, and exiting when optimization completes.
Recommended use: The help recommends using DEFRAG occasionally or after installing larger programs or creating many small files.
Operating context: The help describes fragmentation as a normal process on DOS disks that can slow file access.
Errors: The documented exit codes include disk-too-full, read-error, write-error, FAT-allocation, and memory errors.
Distribution: The FreeDOS 1.4 distribution is downloadable in LiveCD, USB, LegacyCD, and floppy editions.
System requirements: The FreeDOS download page lists an Intel CPU, BIOS or UEFI Legacy mode, 640kB memory, and at least 20MB of hard disk for installation.
Compatibility context: The FreeDOS project describes its system as DOS-compatible and says programs that work on MS-DOS should also run on FreeDOS.
Security and compliance: The opened DEFRAG help and download pages do not state security certifications or compliance claims.
