Disk Space Recovery Wizard can reclaim up to 500MB of wasted disk space. If you have converted your hard drive from FAT or FAT 16B to FAT 32, you should have gained a few hundred extra megabytes however, on using this disk wizard you should gain up to approximately a few hundred more megabytes. When programs access the Windows system, they leave wasted binary and hex data lying around, which eventually fills the hard disk. The Wizard finds those areas of the hard disk that contain this garbage data, checks to make sure no program is using it, compresses it, recovers disk space, and then deletes this data.
