The only limitation is in Windows, where I believe the first operating system must be on drive C:, but otherwise any virtual drive has the same features as a physical one. Your computer will see these imaginary disks as being real, and will display them in your file manager exactly the way your C: drive is displayed, and you will use them the same ways.

Even just having one virtual disk for movies, one for games and so on will make your life easier when negotiating up to a terabyte of data on the most recent drives. Each one could be allocated a different use, or even a different operating system, allowing you to run various versions of Windows side by side (oh joy!) or, more often, to run Windows and Linux alongside each other. This can be very handy, especially with today's huge hard drives, as you can easily create a drive E, F, G and right through to Z if you feel like it. If that made no sense at all, 'partitioning' is a way of dividing up your big physical hard drive into imaginary, or 'virtual' drives, each called a partition. It has a very straightforward and easily understandable graphical interface which shows you exactly what space you have on your disk, and what it's used for, which is most often going to be a combination of NTFS and Linux partitions with possibly some unallocated space. The freeware version of this little disk partitioner is all you'll need to handle your disk space, though if you want to take an even greater chance of screwing your system up there is also a 'pro' version which allows you to do scary things like changing cluster sizes or hiding and unhiding partitions.
