I MUST RECCOMEND this program.
Raxco Perfect Disk.
Anyway you can get your hands on it, DO IT, I promise you wont regret.
Perfect disk is a disk defragmenter that is unique in many ways.
Namely, that it not only defragments your files (can be specific!) or Drive, but it places the defragmented files IN A SPECIAL ORDER.
For example, it places the files that are used for bootup towards the front of the disk platter SO!! the head accesses it faster.
ALSO, it defragments a file that is extremely crutial to the bootup, and general speed of your PC, but a file that the ordinary windows defragmenter (which you should use tonight before you sleep btw
) CANT defrag.
Your Pagefile (pagefile.sys) file - which acts as VIRTUAL memory.
You do a smart replacement defrag, an offline degragmentation (of all the system files) and then another smart replacement defrag, and i PROMISE you - you're PC will move faster
