Before you defragment, you should scan your disk for errors.
It's always best to defrag a disk when it's not in use. To set up Windows to defrag a drive automatically at such a time, start by opening Notepad or another text editor, and type defrag.exe followed by a space, the drive letter, and a colon.
UR command line might look like this: defrag.exe c: -f -v >"e:\doc\defrag report.txt" (your path and file name may differ, of course). Press Enter.
If you want to defrag more than one drive, create a command line for each one, changing the drive letter and the file name and path as necessary. When you're done, choose File, Save, and save the file to a convenient location.
Make sure to use the .bat or .cmd file extension.
Now any time you want to defragment the drives, just double-click the .bat or .cmd file you created.
Finally, Windows' Scheduled Tasks utility lets you defragment automatically at the time of your choice. Make the disk defragmenting occur whenever you want.
HAPPY DEFRAGGING
