I am a firm beleiver that Defrag works. Even if todays Hard drives have
multiple heads, it will cut down on time if related files are in the same
area and the computer doesn't have to spend miliseconds scanning and
searching. Sure a milisecond isn't very long, but have you ever seen how many
files are needed to allow a program to function? now if they are scattered
add a few miliseconds to for each and every file that needs to be found, now
it isn't miliseconds any more. Not counting the lines of machine code within
the files that can also be scattered.
I run diskcleaner, empty all of my cache, run ccleaner and then go to my
browser and empty all of my temp files etc. once done I run defrag at least
three times. I do that bout once every two weeks or so.
For a quick brief what defrag does, imagine a file cabinet, a very LARGE
file cabinet. Now for every program you add a drawer, some programs may
require more than one drawer. Files are in order and everything is great, you
are able to go to the cabinet and grab a file with very simple effort.
Over time, many people have used the cabinet and what happens is if a
program is removed and if the drawer becomes empty, it would be best to have
that empty drawer at the bottom or end of your cabinet. Leaving it, means if
you install another program that takes up a drawer and half, it will filll
that drawer and then go to the next place where there is room and drop more
file folders and then continue on until all of its folders and files are put
somewhere. SCATTERED, when the Hard drive needs to pull files in ORDER, it
may find one here and then there and another several drawers away etc etc.
DEFRAG, rearranges so all related files are together and everyone lives
Happily Ever After... end of story....
