I was bored so I wrote this defrag script that will defrag all volumes on a system. This includes HDD partitions only. @echo off set logfile=c:\defrag.log :: Check for old files set oldfiles=drives drives.log drives.txt new.txt newlist.txt final.txt for %%i in (%oldfiles%) do if exist %%i ( del /q /f %%i > nul ) if "%logfile%" == "" ( goto :no_log ) else ( goto :log ) :log echo Defragger started at %time% on %date% by %username% on workstation %computername% > "%logfile%" echo. >> "%logfile%" echo. >> "%logfile%" :: Enumerate the Windows registry for valid mount points for /f "tokens=1 delims=:" %%i in ('reg query hklm\system\mounteddevices ^| findstr \DosDevices\') do ( echo %%i >> drives ) :: Remove \DosDevices\ prefix from the drive letters for /f "tokens=3 delims=\" %%i in (drives) do ( echo %%i >> drives.txt ) :: Append a semicolon ':' to each drive letter in drives.txt for /f %%i in (drives.txt) do ( echo %%i: >> drives.log ) :: Check if drive A: exist because we don't need to defrag your floppy drive ;-) sort drives.log >> new.txt type new.txt | findstr "A" > nul if errorlevel 0 for /f "tokens=1 skip=1" %%i in (new.txt) do echo %%i >> newlist.txt :: Check whether the drive is a hard drive or another type of drive for /f %%i in (newlist.txt) do fsutil fsinfo drivetype %%i | findstr "Fixed" >> final.txt :: Hide temp files so they don't get accidentally deleted before Defragger finishes ;-) for %%i in (drives drives.log drives.txt new.txt newlist.txt final.txt) do attrib +h %%i :: Now check whether each drive needs to be defragged and continue accordingly for /f %%i in (final.txt) do ( defrag -a %%i | findstr "should" > nul if errorlevel 0 title Defragging %%i && echo Defragging %%i && defrag %%i >> "%logfile%" echo. echo. echo Defrag on drive %%i completed at %time% ) echo Defragger completed at %time% >> "%logfile%" echo Defragger completed successfully ::Now we cleanup all the temp files del /q /f drives > nul del /q /f drives.txt > nul del /q /f drives.log > nul del /q /f new.txt > nul del /q /f newlist.txt > nul del /q /f final.txt > nul :: Mission Complete echo. echo Log file saved to %logfile% echo Would you like to view the log file now?
