The program just allocates the space needed (it doesn't initialise it in any
way) which means that it is extremely fast, and useful for creating large files
like hardfiles or other disk image files for use in emulators (like E-UAE
f.e.).

Usage:

mkfile FILE/A,SIZE/M,SIUNITS/S

To create a 1 byte file called test:
mkfile test 1

To create an ADF file:
mkfile empty.adf 880kb

To create an 8 GB hardfile:
mkfile empty.hdf 8gb

To create a 1199571022 byte file:
mkfile blah 1gb 120mb 78b

To create a 1120000078 byte file:
mkfile blah 1gb 120mb 78b siunits

supported units (the 'b' can be optionally left out):
b, kb, mb, gb, tb
