I am probably the only one who has the smallest amount.
My entire hard disk drive used space is 12.5 GB and this is what I have:
-Microsoft Windows XP Professional edition with the service pack 1,2 and 3 32-bit edition computer operating system
-Around 40 installed programs together with the Microsoft Visual Studio .NET
-1 game
-Neccessary Windows OS components needed for programming such as .NET 1.0 and so on...
-Also my page file on my 32-bit OS is at the maximum which is 4096 MB or 4.0 GB
So as you can see I have a lot of stuff and the total size is ONLY 12.5 GB.
I must admit that it took me some time to find a way to make ALL THAT to take so small amount of space.The reason why I wanted it to make it to take the smallest amount of space as possible is because I need that to fit on 3 DVD-ROM disks of 4.37 (4.7) GB in the case if I ever decide to burn my cloned HDD on 3 DVD-ROM disks.Because I do not want it to take more than 3 DVD disks lol.
Of course Windows 7 OS size is bigger,but if you do not do things properly and collect a lot of trash and junk and never clean unneccessary junk then the entire HDD size can increase a lot.
By the way...I just came back from the hospital few days ago.The operation I had on mandibula did not go so well and I will probably need to go in the damn hospital next week again.Life sucks lol!
Cheers!
