If you have a lot of data on multiple hard drives, it’s important to defragment them all at once. This will help free up space on the drives and make them more efficient. To do this, open Windows Explorer and navigate to the drive where you want to defragment your data. Then right-click on the drive and select Defragment Now. When the Defragment Now window opens, you’ll be asked to choose which hard drive to defragment. If you have more than one hard drive, choose the one with the most data. Once you’ve chosen a hard drive, click on the Define button. This will create a new file called “defrags”. This file will contain all of your data defragged together. Now close Windows Explorer and reopen it so that your new defrags are active. You’ll see that your data is now much faster and easier to access!


The method we are going to use is by creating a batch file to defragment all of the drives, one after the other.

The disk defrag utility in Windows XP can be triggered from the command line with the following syntax:

First, we’ll create a file named defragall.bat, and place it anywhere you like, as long as you’ll remember where it is. If you want to run it from the command line, you could place it in the \windows directory so that it will be available in the system path.

For each hard drive, add a line to the batch file. For instance, if we want to defragment drives C: , D: , and F: we will add these three lines:

To run the defrag, just either double-click on the batch file or start it from the command line.
