When people need to do this, they look up PARTITION MAGIC.
My computer's 80mb hard drive is partitioned into "C", "D", and "E" drives. Windows XP and all my applications are installed on partition "C" (40 mb). Partitions "D" and "E" (20 mb each) are nearly filled up with MP3's. I have packed a lot of data on the "C" drive as well; programs, images, etc., and my computer is slowing down as a result. I would like to move the MP3's on partition "D" to an external drive. Is there a way to re-allocate the 20 mb on the "D" partition to the "C" partition, or do I have to reformat the whole drive?
