Answer 2

What the defragmenter is, and bare with me for a minute, is basically rearranging your hard drive.

Let's say, for example, you put a large file on your computer. It is going to save it to the hard drive, and it needs to find room for it, so it will break it up, and find openings here and there to store it. This is good to store it, but it will slow down the computer next time, because then the computer must look through the whole hard drive, to find the file.

When you defragment, it basically picks everything up, and drops puts it together like a puzzle, so everything related is together, and it can run faster. This also free's up space, because there may have been small openings on the hard drive here and there that were not big enough for a file, put all those free openings together, and you get quite a bit of free hard drive space.
It soudns complicated, but it is basically like cleaning it up every once in a while, to maximize seek times, and free some space.

Answer 3

The easiest way of explaining this is by picturing this to be a very long filing cabinet (your hard drive) with non-movable hanging files (Your Files). Each file (some large and some very small) all take up space in this cabinet. When you delete a file, it is just like removing a hanging file from the cabinet, and now you have an empty space where the file used to be.

Now here is where it gets tricky and exactly explains what fragmentation is:
now you have a filing cabinet with several empty spaces, and you want to save a file to this cabinet, but there isn't any one space large enough for this huge file........your computer spreads this file over all the empty spaces........so you have FRAGMENTATION of your files. A defrag will attempt to move these fragments around, reassemble them into contiguous data and arrange the files in such a way it is easy and fast to retrieve.

Fragmentation causes slowness in the same way that it would take you a more time to pull together a fragmented file from several spots and reassemble said file as you go....each time having to refer to a reference table so you know where to pick up the next piece....compared to just going to a single spot in your cabinet

Answer 4

The file is in a million pieces taking up space , the defrag sweeps it all together giving you more space.

Answer 5

defraging won't make more free space..when computer writes data to your hd it may write it to different places and over some time it would take longer to read the data..defraging just organizes all data on your hd for faster access..that's all..lol...it will make your puter work faster but you won't have more hd space....


p.s. cashmatt1..looks like the book didn't help you...

Answer 6

Defragmenting your computer takes your fragmented files and either fixes them or deletes them. Also it compresses files and that is why it gives you all that free space. Hope this helps!
