can anybody tell me where can i create a virtual hard disk i need one for my computer and thank you all

Hi,
There are many options.
Just do a search for "Virtual drive" or similar.
However for a start, here is a link for some freeware apps:

apart from creating one on a harddrive,you can also create them on an server on the internet.
hope this helps
