But how much was actually used space?  More than 350Mb?
If not, that's pretty lousy compression.  If you had
a program that would force 0's into all unallocated space,
your compression ratio on the unused area would be virtually
infinite.  Couple that with decent data compression, and
you could shrink the size of your image immensely.
