A rudimentary but handy tool for calculating the compression ratio or post-compression size of a file and the number of cylinders, heads, and sectors on single-sided data storage disks.
It can be useful for determining the geometry of virtual hard disk images for Bochs, PCem and DOSBox and estimating possible space savings on drives compressed with DriveSpace.
