I got some unallocated space on same hard drive and want to allocate that space to c drive. any simple method preferably without using third party tools
Windows XP will not resize or extend partitions to adjoining partitions or unallocated disk space... you have to use third party tools to do it... try Active Partition Manager 1.3 this edition is portable.. it apparently installs but it's only the standalone file, a log file and a settings file.
