Put simply - it's the breaking up of a file into pieces so it can be saved to disk.

When you save a file, Windows simply looks for the first available free-space on the disk. It then saves the file - whether it will fit or not. If the file fits the free-space - end of story. If the free-space gets filled before the file is saved, Windows looks for the next available chunk of free-space and saves what's left of the file. The computer repeats the process until the entire file is saved.

Defragmentation - is a small program that uses existing free-space on the disk to 'join' all the fragments of a file together, before saving the file as one complete 'chunk'. If you have a lot of files on your hard-drive, it's a good idea to run defrag on a regular basis - that will help speed up the time the computer takes to process files.

What is disk fragmantation?

Defragmentation is a process that reduces the amount of fragmentation in file systems.


When disk defragmenter is completed why does it use or takes storage space on that disk?

Defragmentation is the process of rewriting non-contiguous parts of a file to contiguous sectors on a disk for the purpose of increasing data access and retrieval speeds. Because FAT and NTFS disks can deteriorate and become badly fragmented over time, defragmentation is vital for optimal system performance.


When does a person use disk defragmentation?

A person should use disk defrag weekly to keep computer from slowing down but you only have to do it when it does slow down.


What is file defragmentation?

Disk Derangement is a tool that rearranges the data on your hard disk and reunites fragmented files so your computer can run more efficiently.


What maintenance operation should be performed to prevent a slowdown in data access speed?

Disk defragmentation.


What does it mean if a disk is fragmented?

If a disk is fragmented, this means that the files in your computer are spread out all over the disk taking up too much space. This can be corrected by defragmentation which consolidate all the data.


Which windows utilities would you use to realign the file structure on the disk to optimize performance?

How does disk-defragmentation work?

Go to Start then all programs, put your mouse on accessories then system tools and click on Disk Defragmenter. It moves around files on your disk so that they are not so spread out so your disk has to spin less.


What are the main benefits of disk fragmentation in Windows?

Disk defragmentation is the process of consolidating fragmented files on a computer's hard disk. The main benefit of doing this is to speed up a computer that has slowed over time.


Can you stop disk defragmenter halfway through a session?

Yes, you can cancel the defragmentation process before it is complete. It is probably a good idea to re-run the defragmentation at some point in the future, but failure to do so will not harm your computer.

What is the advantage of disk defragmentation?

Disk defragmentation helps to keep the HDD activity smooth and fast thus preventing lags in the opening of files, programs etc. Another important advantage is that if you defrag regularly, you dont need to wait for ages before your PC starts or shuts down. It contributes to maintaining good speed and performance of your system.


Why you do Disk Defragmentation?

When files are created/edited/deleted they cause gaps in your hard drive structure. When a high level of fragmentation is reached (15% and above) your system will become slower as your hard drive has to look through a structure which now has several gaps which cause slower response times. Using disk defragmentation tools allows these gaps to be closed and all your files moved into easily read blocks for your hard drive to search through in times to come. -------------------------------------- Defragmentation also moves the most used files to the begining of the disk for quicker access.


What is the difference between disk clean up and disk defragmentation?

Disk defragmentation organises the file structure of harddisk by gathering files that are stored in fragments & piecing them together to form a large fragments. It makes the drive function more quickly & reduce the amount of hops to read single file. Disk clean up will delete all the junk & temporary files & will increase the speed of ur computer by creating more space


Why are some defragmentation tasks scheduled in the middle of the night?

If a system is on 24-7, scheduling defragmentation for off-hours means there is less activity on the computer, thus less disk access and no one running applications whose performance might be affected.


What are defragmentation utilities?

They are tools to re-arrange the space in a hard disk trough time all files in the hard disk need to be arranged so the hard disk can have more life and your computer will operate smoother.


How do you defragment a computer?

Use a defragmentation tool. In Windows, you can do this using the Disk Defragmenter tool, which is accessible from Start -> All Programs -> Accessories -> System Tools -> Disk Defragmenter.


What is the advantage and disadvantage of defragmentation?

Defragmentation leads to performance improvements, when used with traditional disk drives, when accessing data which was previously scattered across the surface of the media. This is because head movements and cluster seek operations are reduced in numbers, as the scattered data is combined into fewer, larger, chunks. Note that this effect only applies to those drives which use mechanical and moving heads; any solid state drive will not benefit in this manner. The primary disadvantage of defragmentation are the substantial processing requirements; defragmenting a drive is time and power consuming, and it is generally not advisable to use the disk for any other purpose during this process, as this further slows down the process, and might reduce its effectiveness. Another significant disadvantage of defragmentation is the inherit risk in the operation. Defragmentation re-organizes data on the disk on a very low level, and any error in the process, caused by power failure, disk failure, or software errors in the defragmentation software itself are potentially unrecoverable and severe. With the emergence of increasingly fast drives, the growing popularity of sold-state drives, modern file systems (less prone to fragmentation), and clever caching strategies built into modern operating systems, defragmentation is considerably less important and beneficial than it once was, as its disadvantages begin outweighing the benefits.


What processes can be changed through system tools?

System tools can handle processes such as defragmentation of the disk, disk cleanup, and file removal. Using this provides an efficient and centrally controlled way to keep a computer running smoothly.


How does disk defragmebter works?

It puts files into one block, whereas before defragmentation it is still one file, but may be stored in different sections of the disc.


What do you do if you want to run Skype but it says your disk is full?

I don't know what computer you have, but if it is windows you can run a defragmentation of the drive, dump your unused programs, and clean memory.


What is the function of disk defragmentation?

In some file systems, writing and erasing files will eventually split the files into many separate physical locations (fragments) on your hard drive. This can cause excessive waste of space (many blocks of the harddrive may only be partially used) and many movements of the head that reads the disk when reading just one single file. Defragmentation addresses this problem by collecting fragments of files into contiguous (unbroken) areas of the disk. Resulting in quicker read times and less wasted (unacessible) areas of the disk. ----------------------------------------------------------------------------------------------------- I tend to think of a badly fragmented and cluttered drive as a messy closet or desk where it takes double the time to find anything. Disk defragmentation organizes scattered file fragments on the drive in such a way as to speed up the data access leading to faster opening of programs and files.
