Is it possible to enlarge an installed (Windows XP) virtual disk partition?
I'm using vmware player (vmplayer) on ubuntu linux. If not, can vmware workstation, or -server do the job?
Yes it's possible. It's a two step process:
Of course, you should backup your virtual disk files before doing this in case anything goes wrong. But, I've both grown and shrunk NTFS formated vmdk files several times without a problem.
