Reorganizes the files on a disk to optimize disk performance. Do not use this command when Windows 2 or 3.x is running (note: Win9x no problems.) Syntax DEFRAG [drive:] [/F] [/S[:]order] [/B] [/SKIPHIGH] [/LCD | /BW | /G0] [/H] DEFRAG [drive:] [/U] [/B] [/SKIPHIGH] [/LCD | /BW | /G0] [/H] Parameter drive: Specifies the drive that contains the disk you want to optimize. Switches /F Defragments files and ensures that the disk contains no empty spaces between files. /U Defragments files and leaves empty spaces, if any, between files. /S Controls how the files are sorted in their directories. If you omit this switch, DEFRAG uses the current order on the disk. The colon (:) is optional. The following list describes each of the values you can use to sort files. Use any combination of the values, and do not separate these values with spaces. N In alphabetic order by name N- In reverse alphabetic order by name (Z through A) E In alphabetic order by extension E- In reverse alphabetic order by extension (Z through A) D By date and time, earliest first D- By date and time, latest first S By size, smallest first S- By size, largest first /B Restarts your computer after files have been reorganized. /SKIPHIGH Loads DEFRAG into conventional memory. By default, DEFRAG is loaded into upper memory, if upper memory is available. /LCD Starts DEFRAG using an LCD color scheme. /BW Starts DEFRAG using a black and white color scheme. /G0 Disables the graphic mouse and graphic character set. /H Moves hidden files.
