# Sets the amount of preallocated disk space in bytes. Disk space
# preallocation allow to reduce physical file fragmentation and to make
# database work in out of disk space condition. When preallocation enabled
# engine allocated 1/16nth of already allocated disk space at a time but
# database work in out of disk space condition. When preallocation enabled,
# engine allocate 1/16nth of already allocated disk space at a time but
# not less than 128KB and no more than DatabaseGrowthIncrement (128MB by
# default). To disable preallocation set DatabaseGrowthIncrement to zero.
# Shadow database files are not preallocated
