How to perform disk defragmentation
Disk defragmentation is a process that reduces the fragmentation in file systems. Imagine you are in an office with a 1000s of files everywhere and you did not know where they were, having to search a long time to find them, by tidying them up and putting them back into the correct place you can find them quicker and easier. This is what disk defragmentation does, it puts the files back into their correct place, where they can be quickly and easily found by your PC.
What you'll need:
PC running Windows
Click START > ALL PROGRAMS > ACCESSORIES > SYSTEM TOOLS > DISK DEFRAGMENTER
Now the program will start, click ANALYZE DISK, this will analyse the disk(s) (Which may take some time).
Wait for the disk(s) to be analyzed, then if it may tell you 1 or more of your disks need defragmenting,if so click DEFRAGMENT (This may take some time, depending on how defragmented your disks are). If not, exit.
Be patient, this may take some time.
