most programs put hooks into windows so they need to be on the same drive with windows...
partition your drive into 3 approx equal parts...I like logical drives but you could set them up as partitions if you prefer....use QParted to do this before you even load windows...
install the OS to the C: as soon as you get it installed...defrag the drive...then set the swap file size ...the minimum and maximum to the same number...it should be 1.5 times the amount of installed ram...this puts both the OS and the swap file on the fastest part of the drive...then install your programs to the C: ...after install a few defrag again...on the second partition/or logical drive...move my documents folder to this area...also set it so all your downloads including programs go there ...when you install the programs let them install to the C: programs folder...that is the fastest part of the drive...
move the my documents folder to the second partition/drive...
The ideal time to relocate the My Document folder and other system folders is when you have just bought a new PC and have yet to load your data or applications.
Click on the Start button and then right-click on My Documents and select Properties. If there's no My Documents in your start menu then right click on the My Documents icon on your desktop instead.
When you've clicked on properties, select "Move" and then navigate to your D: drive. Select the drive letter and then click "Make New Folder." Enter "My Documents" as the folder name and hit Enter and then OK. Windows will then ask you whether you want to move your documents; click Yes.
this puts your music and photos and the like to the second partition/drive...this will keep the C: drive uncluttered and in case you ever have to reinstall windows your data will be safe on the second partition...saves some time
Moving your documents make take some time. Once moved, though, you can access them normally from the "My Documents" icon on the desktop or elsewhere.
In the process you'll free up a lot of room on your C: drive. Defrag the drive so it can be utilized by Windows in the most effective manner.
