^ Here's an explanation on defragging... [quote]First, an explanation of what fragmentation is. [b]Fragmentation occurs when you write and delete files to your hard drive.[/b] Every time a file is deleted you free up space. When you write to the drive that free space is used. If the file being written to the drive is larger than a piece of free space then another piece of free territory is taken elsewhere on the drive. Over time you end up with a file that looks like this: [quote][b]hard is read This to[/b][/quote] You can make sense of that, but, it took you some time to figure it out, right? Your hard drive has to go through the same period of figuring as well. The more fragmented your drive, the longer it takes for the computer to figure out where all of the little pieces are and put them back together again. By defragmenting the drive [b]you gather up all those scattered pieces and place them into order[/b] in one area once more. The above example would then become "This is hard to read" after defragmenting. Much easier to read and much faster to read as well.

But 1st I recommend you uninstall Corel first before defragging.
