In their own words
FreeDOS Defrag
FreeDOS Defrag, or DEFRAG, is a free, open-source DOS utility that rearranges file fragments to improve loading times from a specified drive. It offers a menu interface and a command-line mode selected with /C. Full optimization with /F places files at the beginning of the disk without gaps, while /U unfragments files but may leave gaps. The /S option sorts files by name, extension, date and time, or size, with descending order available. Other options support quick defragmentation, rebooting after optimization, and exiting when work finishes. Its help recommends occasional use or running it after installing larger programs or creating many small files. Documented exit codes cover insufficient disk space, read, write, FAT-allocation, and memory errors. DEFRAG runs in the FreeDOS environment, whose 1.4 distribution includes LiveCD, USB, LegacyCD, and floppy editions.
