Autumn is, apparently, the time for the launch of new hard drive partitioning tools.
Before it, apart from a couple of small shareware tools, the only way to create or re-size your hard drive's partitions was to back up all the data first, as it was sure to be annihilated. Changing partition sizes without data loss is now as easy as falling off a swivel-chair. So a 1KB file will only consume, say, an 8KB cluster rather than a 32KB cluster, saving 24KB per 1KB file. There are other reasons, too. You may want a separate partition for a swap file, or to manage your data more efficiently.
