About Your Hard Disk Drive
To improve the performance of Sony audio and video software applications, the hard disk drive on your computer has been
formatted with two partitions, C and D. Some Sony software applications save files to the drive D partition. This prevents
large video captures from consuming the available space on your drive C partition.
To maintain optimum system performance, you should defragment your computer's D partition regularly.
