Windows 7: Is more free space in win. installed drive incr speed

Is it true that the more space we have in windows installed drive will more increases the speed and performance of computer ????

well yes but over a period of time as the hdd fills, the system will take longer to find the files you need so having a knock on effect of slowing the pc down, so on a fresh install you have a fast pc

The free space will help you even more, if you defrag every now and then.

So If I increase 10Gb space (from 20Gb to 30Gb) to drive C then it will make my computer more faster .

The more free space, the better.

• Keep your Drive Defragmented as much as possible.
• Use some of your "Free Space" to increase the size of your Windows Page File to reduce the amount of RAM used.
• Constantly clean your computer (Temp Files, Net Cache, Cookies, etc..) by using something like CCleaner.

Those 3-Steps above will maximize your Hard Drive Performance and life-span.

Up to a point it matters. For example, if your computer hard drive is nearly at 100% capacity...so you will be dealing with a lot of extra fragmentation and such.

However, if you have a 500GB hard drive and are only using 35GB...It's not really going to change performance if you go from 460GB free to 430GB free of even 350GB free.

So, I would not go to any extraordinary lengths to keep my hard drive as clean as possible in hopes of seeing increased performance.
