Partitioning More Space

[Healthycola]

I have Windows 7 installed on my PC. When installing Ubuntu, it gave me the option to only allocate 20 gigs of space for it. Is it possible to increase that amount? Is it possible to do so if Ubuntu is installed on my PC already?

You can just use GParted, everytime you want to 'part'(ition) your hard disk drives.
